It has been very typical Sonoran Desert winter weather, daytime highs in the 60’s and lows in the 40’s. Perfect, in my opinion. On New Year’s Day the forecast is for rain. I’ve been on a search for Black-chinned Sparrows, which I usually can find in the mountains around the area, but so far, I haven’t found any. The Ajo Mountain Loop Road in Organ Pipe Cactus National Monument is the best place to find them, but it is closed for repair until mid-January. I’ve been having some nice hikes though.
I know that the folks back in South Dakota aren’t going to have much sympathy for me here. But it has been pretty cold for this area, and it has been a long-lasting cold snap as well. The end is near though as a warming trend is finally coming. Daytime highs in the low 50’s will soon be in the upper 60’s and 70’s. The Ajo CBC was held on Friday, and I had my usual unit. A Spotted Towhee was probably the best bird for me, and I got the other two species of Towhees as well, Green-tailed and Canyon, all within 100 yards of each other. Another good find was a Canyon Wren, and I got some nice photos of that. Astrophotography has been slow and cold. Quite a few cloudy nights and the nights that were clear had heavy dew that later froze on surfaces.
I’ve had two trail cams out at Highway Tank for a couple of weeks now. I am trying for the Mountain Lion that has left tracks there but so far, no luck with that. Here is a YouTube LINK to a video I captured that is described by the title to my post. I find it amazing that something like this would happen right in front of my camera. The cameras are still there so maybe I will have a lion to show soon. The weather has been very nice and I’m enjoying the warm days.
Happy Thanksgiving! I’ve been keeping busy. Birding, astrophotography, and hiking. Now I’m working on digging up 89 photos of butterflies for Gary Marrone’s 2nd Edition of The Butterflies of South Dakota. That will be a great book when it is published. Weather here has been cool but still pretty nice.
I’ve been wanting to do this since I got here, but my knee hasn’t. My left knee has been pretty sore since I left South Dakota but is slowly getting better. Today, I tested it out on Alamo Canyon, and it did fine. The park biologist, Danny Martin, told me he had seen some good butterflies there this summer, including Tropical Leafwings and Zilpa Longtails. The Zilpa Longtail would have been a lifer, but I couldn’t find any today. Probably getting too late in the season, but there were still some Tropical Leafwings, and I was very happy to get the best photos I have ever taken of that species. I saw some Tropical Leafwings years ago at Miller Canyon but had poor luck photographing them.
The full moon is coming back strong now but I had some good nights over the last few weeks. I’ve been thinking about what I can do to improve my astrophotography and I think my best bet is a dedicated astro camera. I’ve been using an old Canon 7D MII that was modified for H-alpha. The images are always pretty noisy though and hard to process. So, maybe in the near future there will be change.
It was December of 2017 when I saw my first nighttime rocket launch from Vandenberg Air Force Base. I had no idea what it was and was not prepared for photos. I managed to get a few that were handheld and poorly focused, which can be seen at this LINK. Since then, I’ve been waiting for another opportunity and last night I got it. I have subscribed to Launch Alert and I knew this one was coming. Vandenberg AFB is now Vandenberg Space Force Base, it is about 500 miles west, on the California coast. This rocket is a Space X Falcon 9 that was launching 53 Starlink satellites into orbit. The timing of the launch put the rocket and the exhaust in the light of the setting sun while I was far enough east where it was dark enough to see it. I was set up with the Canon 6D and 35mm Sigma lens on a tripod.
I arrived in Ajo almost a week ago. I’ve been waiting to accumulate some new photos before posting an update. The area has had a good monsoon season, everything is green, and all the tanks and ponds are full of water. The bird migration is building up slowly here, so far nothing very exciting. I had a Kit Fox near the camper last night while I was out doing astro. It is good to be back in the Sonoran Desert.
The Slim Buttes area was getting pretty crowded with the opening of archery deer season and the Labor Day weekend. I decided to move back to Pierre for a while. Last night, I was about to go to sleep but decided to check Spaceweather.com one more time to see what the aurora was doing. There was a geomagnetic storm in progress, so I loaded what equipment I needed and drove north of town. Rural Hughes county is not as dark as Harding County but it is pretty good. The only problem was the moon, it is about half phase now and was still above the horizon. By midnight it was sinking below the horizon and conditions improved a lot. This was far from the best displays of aurora borealis I’ve seen, but it has been at least a decade since I’ve seen one this good!
The last few nights have been clear and dark. This area has the darkest skies to be found anywhere in North America and it is pretty amazing at night with no moon. I can see the Andromeda Galaxy with no difficulty, even without binoculars. I set up the Losmandy G11 and used the 500 f4 for a dark nebula and a comet.
I will have to leave pretty soon. I have an appointment in Pierre Monday morning. It is going to be hot there!
