Gustav and Hanna Looking for a Place to Land

These two storms look like they could really do some damage once they reach the U.S. coast.  Right now both are predicted to reach hurricane status over the weekend and then hurricane Gustav looks like it will go to the Louisiana side and hurricane Hanna the Florida side. Sorry no photography posted other than the hurricane graphic, I will get back to posting some images soon.

On an interesting note.  I work with domain information and registrations and often buy domains for my personal or business use.  Did you know that all hurricane domain names have been purchased by speculators through the end of the current hurricane name cycle. Right now, hurricane names are release up to the 2013 hurricane season.  If you take that list and look at some of the unique names on the list, then compare them to registered domain names (like hurricanenestor.com), you can systematically go through the list and see they are already reserved as far out as 2013.

Domain names are the last relestate frontier, and most are worthless, unless you actually want to use one for your name, business, or product.  Some Karen out there might be a windy kind of gal and want the domain hurricanekaren, but your name is on the list for 2013, so sorry, you missed that one.

Tropical Storm Outlook Really Heats Up

Have you checked out the weather in the tropics lately.  Wow, now there are 5 active areas of concern including Hurricane Gustav and now Tropical Storm Hanna.  It had been very very quiet over the last few hurricane seasons and it looks like this year is turning out to be quite a bit busier.

An Alabama Drought Says, Thanks for the Rain Fay

Tropical Storm Fay made its way across our corner of Alabama yesterday and last night, bringing some great rain to a drought area. Tornado warning after warning came and went, but the most we got here is a good solid day of soaking and some wind. A great day to stay inside and watch the weather.

Humidity, Storms, and Lightning in Alabama are Back

We have been in a drought for about two years now. Just over the last few weeks we have finally started to get back those 90% humidity days with afternoon thunderstorms. Finally, the grass, trees, plants, and everything else that needs water is getting a small break.

Lightning in an Alabama Summer Storm

Taken on Monday night as a storm blew through. It was so nice to see a few storms roll through here in the last few weeks. It has been so long since we have had rain here in the lower south, it is a very welcome sight. It also gives me a great chance to practice my lightning photography (see photographing lightning post).

How to Successfully Photograph Lightning // Equipment and Techniques

Well we finally got some lightning (and a little rain) over in this part of the state last night. Here is an image I took last night during the storm. One of my most favorite subjects in photography, lightning, always makes for a nice dramatic nature image. It is so hard to get it just right, and it is nature at its most glorious.

How to Successfully Photography Lightning

Safety - you don’t actually want to get struck. If you can be in a protected area, best to not be holding a tall metal tripod during a storm, you might as well go play golf at the same time.  I list this first because it is the most important thing to keep in mind.  When you feel the static charge in the air on your skin, time to head for cover, quickly.  Know which way the storm is moving so you can take action ahead of getting yourself in trouble.

If possible, try to photography lightning from inside a protected area like a house or a car.  This is almost always not possible, but when it is, it gives you a little extra edge to be able to stick around a little longer.  this image above was taken from inside my house on the second floor out of an opened window.  I was protected from the rain and could quickly take cover in the room if the lightning got to close.

Equipment Needed for Lightning Photography

Camera - you need a camera that can do an open shutter exposure. This is usually called a “bulb” setting, where you can depress the shutter release and leave it open for an undetermined amount of time.  This usually means an SLR camera body, film or digital, that you can control the manual setting and change the shutter to “b”.  This is needed just because you rarely are going to know the exact time lightning will strike, but you can probably catch it within a few seconds.  The flash of lightning only lasts a split second, so having an open shutter is pretty much a must unless you have a lightning trip device.

I have used many many camera bodies over the years.  Right now, I am using a Nikon D300 and a Nikon D700 digital SLR, but you can get a nice DSLR now like the Nikon D40, D60, or D80 that won’t cost you an arm and a leg (sorry I know there are also many good Canon bodies as well, I am just not familiar with them).  The point is, any digital SLR will do, even an older film SLR will work great.  I took many lightning images with my old Nikon N70 and N90s film bodies.  The image above was shot with a Nikon D100 which you can now buy used for around $200-$250.

Lenses - You can choose just about any lens and get some results.  I prefer to use something around a 50-70mm lens, wide enough to get a big enough area to actually have a chance to capture the lightning and tight enough to see the lightning when it occurs.  Use to wide an angle the lightning will look pretty small in the frame, use to close a zoom and you reduce your chances of capturing the lightning when it occurs.  If this is a particularly active electric storm, a zoom might work if you know right where to place the camera.  The lens I used for the image above was a consumer lens, a 24-120mm zoom (non VR) taken at the 24mm focal length.

Tripod - A sturdy tripod is pretty much a must.  Not a plastic one or flimsy video camera one, but a heavy metal tripod that you hate lugging around with you.  If you don’t have a sturdy tripod, you can use something like the hood of a car, a window frame or ledge, a rock or stump, anything you can set your camera on to take away the effects of hand holding a long exposure.  At one point I had a very nice carbon fiber tripod (which cost me about $1,500 USD) but it was sold when I didn’t get much use out of it, and I returned to using my old heavy metal Bogen (now also called Manfrotto) tripod (retails for about $200-$300) which works great.

A Remote Shutter Release - this is something that is also pretty much a needed item.  These are not expensive items if you already have a digital SLR camera body.  They attach to the camera on a port usually in the front of a modern DSLR.  I use a pretty fancy one called the Nikon MC-20 which costs about $60 now (I paid about $130 for mine years ago), but you don’t need one like that, any $5-$10 remote trigger device will work.

Know a Little About Weather, Storms, and Which Way They are Moving

You probably want to try to get the lightning that will show up prior to the rain. This is not always possible, but it is hard to photograph during the rain storm that follows a frontal line.  There are many times when you can see the lightning well before the storm arrives.  Once you start to see it, and you can determine which direction the storm is moving, try to position yourself (it that is possible at all) where you are ahead of the storm front and can pack everything away once it arrives.

You don’t have to be a weather expert, just try to look at the clouds, see which way they are moving and try to adjust your location and distance accordingly.

The Color and Brightness of Lightning - Lightning actually comes in a variety of colors.  Each photograph I have taken always comes out with a different color, because the intensity and actually the kelvin temperature of the lightning varies greatly from bolt to bolt when you are shooting.  The cloud to ground lightning and cloud to cloud lightning is most likely going to be your subject, so once you have taken the photo, review the color in your edit process and make adjustments to the proper color you want to achieve accordingly.

Techniques for Shooting Lightning: Exposure, Shutter, ISO, Aperture and White Balance

Technique - the most common way to photograph lightning is to use a shutter release. Open the shutter for a few seconds and wait until you see some light. Then close the shutter. Do this over and over and over and hope that you actually get a bolt in the photo. You will want to use a wide lens to get as much coverage of the sky as possible. Usually once you see some light it will blow out the image if you leave the shutter open any longer, so just a few bolts at a time unless it is really dark. The object would be to try and get several bolts in one exposure. This is not as easy as it sounds, but makes for a great shot. If you try this, think safety first, nothing else.

Exposure - as indicated above, you want to use your shutter release to open the exposure in a few second intervals at a time.  This will be different with each situation because the proximity to the storm, intensity, pollution, ambient light in the area, all effect the exposure.  If you are shooting just as the sun goes down or there is still some light in the sky, a shorter shutter speed (or higher aperture combination) will be needed to reduce the background visibility.  I like to try for anywhere around 3-30 seconds on my exposures.  30 seconds is usually a bit long especially if you are in a big city with a lot of ambient light, but test it out and see what works best.

Aperture - you should already know the correlation of aperture and exposure, so if you are going to want to use a long long shutter speed, use a large aperture like f/2.8-f/5.6 and if you want something around 3-7 seconds, I would choose to stop down a bit more to something like f/8-f/11.  It also depends on how far away the lightning is and how much light you need in the exposure.  Remember, lightning is VERY bright, so you will burn out the image quickly with just the lightning bolt if you aren’t careful.

ISO Speed - I am writing this assuming we are using a digital SLR camera body.  If you are using film, usually an ISO-100 speed film will work.  I have used Fuji Velvia 50 with lightning photography before and did get some good results as well.  For digital SLR cameras, we manually set the ISO speed which is the third factor in determining exposure.  I like to use the ISO-200 setting to get the highest resolution I can get.  But you can use anything from ISO-100 to ISO-800 or more depending on the proximity of the lightning and your exposure settings.  The closer the lightning, the lower the ISO speed I would use.

White Balance - white balance on cameras today is something a little more tricky.  I almost always use the auto white balance setting just because no other pre-set or kelvin setting seems to work because each lightning bolt or strike is different.  I have used the cloudy or shade white balance and had good results with it, but I never know what I am going to get, and the auto setting isn’t any better than anything else.  It is getting better with the newer digital SLR camera bodies, but for lightning is still isn’t quite there yet.  If you are shooting your images in RAW file formats you can always look at each white balance setting in post process editing and see which one you like best.  If you don’t do any post process editing, that is fine to, the results you can get from the straight jpg file will usually look great too.

Image Data Specifics

I decided to just go ahead and copy the exact camera settings from the image above.  I love seeing data from different shots, so listed below is a copy of the exact settings I used to take the image above.  Keep in mind, all situations are going to be different and no two lightning shots are going to work with the exact settings below.  You will have to adjust everything for your situation, but you can see what I used in this image.

This image was one that turned out ok. I took probably 100 within about 10 minutes that did not. It is not an exact science by any means.

Have Fun and Don’t Get Frustrated

This is almost impossible with photography sometimes.  Don’t get frustrated with your results.  Afterall, photography is supposed to be fun (I think) so try to have a good time, stay safe, and shoot a lot of frames.  If you are shooting with a digital SLR you have the luxry of just shooting away and deleting files later.  I may shoot 200-300 frames before actually capturing one image.  I may shoot for an hour and not get anything.  This isn’t a flower that you have in front of you, it is something very unpredictable, so just have some patience and try again and again to get something you like.  The first lightning images I took were scarce tiny little blips of light in the sky, to which my wife said, “what is that?”.  So just keep trying and you will get some good results.

Pressure Washing a Sailboat in a Gale Warning, Really

tow boat on the inter coastal waterwayBefore we left from our other home, we had planned on using this weekend down at the boat as a cleaning weekend. We were trying to beat the Spring breakers who were  arriving soon, along with all the regulars for the summer. We were hoping to hit a slow time in between Spring break, snow birds, and regulars, and I think we managed to do that just fine. Of course, there was just one reason for that. GALE FORCE WINDS.

Temps that dropped down in the 40’s would generally keep most people away from a marina, but the winds were something else. Prior to this weekend it had been starting to get up in the 70’s so we thought winter was over. No such luck. When Deborah starting taking photos of me doing the pressure washing it was rather nice, but a little cool.

As the day went on, it got colder and colder and colder and the wind started blowing so hard that I turned on the weather radio to hear, “gale warning in effect” for the next two days. Oh well, this is when we were going to clean the boat. There were two tasks to complete today, a complete pressure wash, and removing all the vinyl lettering.  A job that didn’t really seem all that hard when we left Auburn and arrived at the marina to a nice sunny, and rather warm day, but oh how things change.

Pressure Washing and a Little Wind

So, I started washing to boat from top to bottom, or as much of it as I could reach. I started off in shorts and a hat and put on more cloths as the day went on. Being able to pressure wash a boat in the slip is a great advantage to having to haul it out or use a scrub brush or something.

Each winter an unbelievable grind and gray matter clings to the fiberglass and finds a home that seems impenetrable. A pressure washer does a cleaning job like nothing else I can imagine. I would highly recommend one to anyone looking to clean anything that can withstand the power of a real, genuine gas powered, not available in California, pressure washer. They work great.

Time To Remove all Lettering

Deborah and I decided to re-christen our sailboat, named the s/v Laughalot, to the name of our company, motto, and a name we picked together about a year earlier, the s/v Island Zephyr. The first step of course would be to remove the lettering and measure for the new graphics.

scott removing letters

From some of the photos you can see that this was far harder than the washing and I think I had a headache for two days after I finished with the transom graphics. We are planning on putting the name along with the registration numbers at the bow, port and starboard sides, then a larger graphic in the back that has the name of the boat, home port (that would be Auburn, AL), and the website address. I will do another post with the actual graphic I have designed and hopefully we can get it made and put on the boat very quickly before someone gets upset with a boat that has no lettering. It won’t leave the slip at all so it shouldn’t be a problem.

As you can see from this last photo, the winds are now blowing quite hard, I am now in long sleeves, and all sane individuals are inside and warm. The photo of the tow boat at the top should have been an indication, they were pulling over and stopping along the inter coastal waterway because it was to dangerous to move the barges. At least we are done. Cleaning and all this is just part of the fun of a sailboat. Everyone else around here will be doing this same thing when it is nice and warm outside and I will be done and up in the cockpit, watching.

A Frozen Car in September Must Mean Colorado

This image was taken just a few days ago. YES, these two photos were taken on September 25th, in Creede, Colorado. Not the most photographic images I know, but we went up to visit some family in Colorado and froze to death in just a few days. The fall weather in this part of Colorado can be brutal, and the winter just miserable. Being from the south, cold is what it gets for two days in February when it gets below 40 degrees, here, at the 9,000 foot level, it gets to be -30*F in the winter, and just plain cold in the fall.

At this elevation, temperatures are well below freezing long before the rest of us even know fall is near. It is one of the most beautiful parts of the country, and the most unforgiving and harsh as well. The Aspens were in full yellow fall colors, frost and all.

Frozen car in Colorado in September

The temp shown above was actually quite warmer than it was in the car. The car read 19.3*F as I took this photo. Just two long days in the car and we were back in the fall in the south, a cool 92*, ahhhh, we can almost turn off the air conditioning now.  The first image is the car, and again, this is September, and the next is of course my loving wife Deborah, showing me how much she loves to be sitting in a frozen car instead of sitting in the Florida Keys.

Aurora Watch: Solar Wind Due to Hit the Earth Tonight

There is so much to look at that effects the radio propagation and certainly a lot to learn if you are new at this, but I found this information interesting and wanted to post it. Thanks to Karen [KI4NGX] for the info. She always sends out a ton of really great stuff on space weather and ham radio. 73, KI4WLR

AURORA WATCH: A solar wind stream is due to hit Earth tonight, possibly triggering a mild geomagnetic storm. High latitude sky watchers should be alert for auroras.

NEW MEXICO FIREBALL: On Sept 13th at approximately 3 o’clock in the morning MDT, an extremely bright fireball streaked over New Mexico, “It was terrifying,” says eyewitness Susan K. Burgess. “I was stargazing outside my house near Santa Fe when the landscape started becoming very bright, as if a brilliant full moon was quickly rising from the southwest. The fireball itself [slowly moved] over the house and disintegrated with a great deal of scatter in the northwest sky.”

At the Sandia National Labs in Albuquerque, a Sentinel all-sky video camera captured the fireball in flight:

Based on data from the video, the visual magnitude of the fireball was -14.6, about four times brighter than a full Moon!

“The fireball was a pure emerald green, uncomfortably bright to look at,” adds Harald Edens located in the Magdalena Mountains west of Socorro, NM. “The object was disintegrating when I saw it, with pieces parallel-tracking and trailing the fireball. Those smaller pieces had all different colors–most notably red. I think it has been a piece of space junk.”

Amateur radio astronomer Thomas Ashcraft not only photographed the fireball, but also recorded echos of a distant radio station bouncing off the meteor’s ionized trail: movie. “This fireball turned night into day!” he says.

2 Meter Meteor Scatter for This Weekend

Comet from NASAI just read the ARRL news this morning and this looks great for this coming weekend. Coming this Saturday there is going to be a great propagation event for those of us on 2 meters who haven’t upgraded to our General yet, or just for those who are interested in making some new contacts.

The information about the shower can be found in several places but the need to know information is below. For a more detailed study of the meteor shower please see the links at the bottom of this post.

The information is posted here in reference to the 2 meter band, but it should provide some good propagation for some of the HF bands as well, I am just not as familar with the HF bands yet.

  • Date - Saturday, September 1st, 2007
  • Time - Peak 1137 UTC (+/- 20 minutes), which is 06:37 CT in the U.S.
  • Frequency - 144.200 mhz for those using 2 meters (can spread out from there depending on results)
  • Meteor Scatter - from Comet C/1911 N1 (Kiess)

This will be the first time I will try to make some contacts via a meteor scatter, so I hope to make some great “2 meter” dx contacts, if there is such a thing. Although it will not be visible from the east coast, we still should be able to take advantage of the propagation at the time (if it materializes).

This very rare shower will occur again on 1 September 2007. A brief shower of tens of meteors will radiate from the constellation of Auriga, many as bright as the brighter stars in the sky. The Earth will be in the thick of it during the one hour centered on 04:33 a.m. PDT. The shower will be visible by the naked eye from locations in the western United States, including Hawaii and Alaska, from Mexico, and from the western provinces of Canada. [Ames Research Center]

I would love to hear from anyone that makes any contacts on Saturday morning, I will be on the air around 1100 UTC (or 06:00 CDT) on 144.200 mhz. Good luck to everyone. 73, KI4WLR

Hurricane Dean Has Been Upgraded to a Category 4

Hurricane Dean 5 Day Track from NOAAHurricane Dean has now been upgraded to a category 4 hurricane and is headed for the Gulf of Mexico. Several amateur radio nets have now been activated, and all the net information can be found at http://www.hwn.org/

Dean looks like it will make landfall around Cozumel and then pass on into the gulf where it should strengthen again before hitting landfall somewhere around Brownsville, TX, according to the more recent forecasts from NOAA and the National Weather Service. Timing of this storm is interesting for the amateur radio crowd since this is the weekend for the large ARRL National Convention in Huntsville, AL. A large number of radio operators go to the Huntsville hamfest each year but this year a larger number will be making the trip because ARRL’s convention going on at the same time. Many hams I know in the Alabama gulf coast have already left the gulf area to go to Huntsville, but all will be keeping an eye on Dean this weekend from up north. 73, KI4WLR
