Astrophotography at the Slim Buttes

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!

This is comet C/2017 K2 (PANSTARRS). It is an Oort Cloud comet with a very long orbital period, it probably took millions of years to arrive at our sun from its origin in the Oort Cloud. It is a very large comet, at about 11 miles diameter. It cannot be seen without at least a 6-inch telescope. In my image, a faint red nebula is visible to the left of the comet. Its current location is in the constellation Ophiuchus. I wanted to get more exposure, but I had to deal with some tall trees that obscured it shortly after it got dark enough for photography.

LDN 1082, a dark nebula in Cepheus. It is also known as Barnard 150. Also known as the Seahorse Nebula. This is actually upside down, I flipped it so the “seahorse” shape is more obvious. The interstellar cloud is so dense that the light of the stars behind it and all other background emissions are completely absorbed. An active star formation takes place almost invisibly inside the nebula.

Flip it again, and it looks like a person walking, maybe with a long cape. So, the Batman Nebula?

While out for a walk a few days ago, this American Kestrel started hazing me. It flew over many times, not happy with my presence. I assume there were young nearby.

More elk, a cow and young calf inspecting something. I had 8 elk pass by in just a few minutes.

A pair of Trumpeter Swans that nested at the JB Dam. Two cygnets can be seen hunkered down on the nest. There are some Painted Turtles sharing the nest with the swans.

A Spotted Towhee that posed nicely for me.

Slim Buttes Update

Yes, I’m still here. I drove into Buffalo today for some ice, groceries, water, and gas. My total expenses since June 17 have been about $250.00, so I’m living cheap for now. I will have to go to Pierre sometime next week. Last night the forecast on Spaceweather.com was for a geomagnetic storm and all I got was clouds in the north. I saw today that many people did see Aurora Borealis last night, as far south as Virginia. I’m sure would have too if it hadn’t been for those clouds. Tonight, will be clear, maybe I’ll get lucky.

The number of elk here is pretty amazing, considering that just a few years ago, there were none. I’ve seen more elk than deer this summer. Apparently, Game, Fish and Parks is having a season on them this this fall, I’ve talked to a couple of people who have licenses and are planning a hunt.

One of the many elk I’ve seen or captured on my trail cams. I had five of them go by at this setup, not a very good angle. It is hard to find a good spot to set a camera, if the grass is too tall or if there are too many tree branches in the view, every time the wind blows the camera takes a 10 second video. Sometimes I will have several hundred videos to sort through. I have to pick a spot with short grass and no nearby tree branches, and also where no one is likely to see the camera and take it. Since I’ve been here in the Slim Buttes, I have captured coyotes, a porcupine, deer, the five elk, and a few Wild Turkeys. Once a House Wren landed in front of the camera and was checking it out. I’ve seen some mountain lion sign and am hoping to catch one of them on camera.

A Red-eyed Vireo, the bright spot behind its head looks like a halo. There was a family group, two adults and three young. I think I was the first human being the young ones had ever seen.

I set up the black light again, a few nights back. This is *Argyrostrotis anilis*, Short-lined Chocolate. First South Dakota record for BugGuide and Moth Photographer’s Group.

Hesperumia sulphuraria, the Sulphur Moth. Mostly a western species with scattered records across eastern North America. Another first for South Dakota.

*Mulsantina picta*, the Painted Lady Beetle. First one I have ever seen and a first for BugGuide in South Dakota. I see a few records in iNaturalist, all in western South Dakota.

Government Hill and Lightning

2 Comments on Government Hill and Lightning

A couple of days ago, the wind finally went down, it seemed like a good time to drive up to Government Hill. It is a good place to look for hill-topping butterflies. It is a couple of miles north of where I’m camped. I have searched the internet trying to find out how it got named Government Hill but there seems to be no information. It may be because of a USGS survey marker on top. Elevation is 3624 ft. There were plenty of common butterflies and lots of flowers, but nothing very noteworthy.

Last night a thunderstorm came up around 2 AM. I wasn’t expecting any severe weather so I was just waiting for it to pass so I could go back to sleep. Suddenly, wham! Lightning hit and thunder roared. The shock wave rocked the Scamp. I thought maybe one of the big trees on the edge of the cliff got hit. I hoped it wasn’t the truck. This morning I found where the strike was, about 50 ft. south of the Scamp. Too close for comfort.

The lightning strike. It blew out large chunks of wood from the pine. Why it hit this tree and not others that are taller I have no idea. Lightning does what it does, just glad it didn’t hit me!

I cannot even find a photo of Government Hill on the internet. No information other than elevation, 3624 ft. It is nice hike, especially on a nice day. This is a panorama of three images taken at 100mm from where I parked. As always, right click on the image and open in a new window for a larger view.

Every time I’ve gone up on Government Hill in the summer I find Coral Hairstreaks hill-topping. This year was no exception.

This is the first time I’ve seen a Gorgone Checkerspot up there. Only one. Other species I saw but didn’t photograph: Two-tailed Swallowtail, Variegated Fritillary, Checkered White, and some other fritillary I couldn’t identify.

A pair of Nuttall’s Blister Beetles on lupine flowers. Lupine is their preferred food plant.

Butterflies and Moths

Last night was fairly warm and humid so I put out the black light. The moon is getting bright and that lowers the effectiveness of a black light for attracting insects, but I did alright. Finally, a break in the humidity too, today is warm but not so humid. It feels good.

A Red Admiral nectaring on Purple Coneflower. The coneflowers are flowering in abundance right now.

A poor photo of a Striped Hairstreak. This is only the second one I’ve ever seen. I couldn’t get a clear shot and then it took off and disappeared. The other one I saw was in the Black Hills in July 2016. I got a better photo of that one, which can be seen at this LINK.

At the black light, a Small-eyed Sphinx. I have seen these in the Black Hills but this is the first time I’ve seen it in Harding County.

An attractive moth, *Haploa lecontei*, Leconte’s Haploa. First South Dakota record in the BugGuide database.

*Hypercompe permaculata*, the Many-spotted Tiger Moth. Also a first South Dakota record in the BugGuide database.

*Marathyssa inficita*, Dark Marathyssa. A very unusual looking moth. I guess the perching pose is defensive camouflage, but I cannot find any reference to it. A first South Dakota record in the BugGuide database. Larval foods include sumacs and poison ivy, both of which are abundant here. The moth is perched on the cord to the black light.

Still at Slim Buttes

I haven’t moved. The weather has been stormy and wet, one storm dropped a lot of hail, but it was small hail. It rains almost every day, but I am not seeing any mosquitoes. No ticks either, I’m not sure why, this area is usually very bad for ticks. Not that I miss them, I can go hiking anywhere off the trails and roads and not get loaded with ticks. One result of that is that I finally confirmed nesting of Townsend’s Solitaire in the pine forests of Harding County. We have known that this thrush species is present and probably nesting, but it has never been confirmed. During the last South Dakota Breeding Bird Atlas (concluded in 2012) Townsend’s Solitaire was still unconfirmed as a breeding bird in Harding County.
