Milky Way — Sept. 16, 2023

The Milky Way above the prairie.

Last night the sky was clear, so I went south with my cam­eras. I got some good pho­tos of the Milky Way just off of High­way 2.

There was a haze to the north, too, so I aimed one of the cam­eras that way. It was­n’t a ter­ri­bly great show—not while I was out—but I did sneak a quick shot of the auro­ra and the PLeaides.

On my way home, the auro­ra picked up a bit, so I detoured onto a dark side road for a few more min­utes. I think I missed the best part of the show, but I did get to dri­ve into a fog­gy val­ley and back out again, so at least there’s that.

It was a pret­ty decent evening, and I was home not long after midnight.

Last night was clear, so I went out to see if I could catch any of the Per­sei­ds. I saw a half-dozen, but I only caught one bright one on camera.

That’s OK, though; there was plen­ty for me to take pho­tos of.

I was out in the dark for a cou­ple hours, and it was worth it.

It was a love­ly night for the auro­ra. It’s too bad I was stand­ing next to my car, bro­ken down on the side of the Trans-Cana­da High­way, while I watched it.

Thanks to my love­ly wife Kath­leen who came and res­cued me, and kept me com­pa­ny while we wait­ed on a tow truck.

Nerdy details: all the pho­tos were tak­en at 11mm, 5 sec­onds, f/2.8, ISO 3200 and edit­ed (light­ly) in GIMP. The panora­ma at the top is 3 pho­tos stitched togeth­er with Hugin

Aurora Borealis, April 23, 2023

Last night, Kath­leen said to me, “I hear the auro­ra should be good tonight.” I checked the app on my phone that shows me the auro­ra data. Every­thing looked pret­ty good except the Bz val­ue, which was about +17. (For a good show, you want the Bz to be neg­a­tive. The longer it’s been neg­a­tive, the better.)

Aurora Borealis

Wow, that was a show.

The data looked ridicu­lous from the out­set. There’s one para­me­ter, when you’re con­sult­ing the ora­cle (sor­ry, the space-weath­er data), the Bz, that you want to be a neg­a­tive num­ber. I’ve seen great shows when the Bz was around ‑3 or ‑5. The longer it’s neg­a­tive, the better.

Yes­ter­day after­noon, every time I checked, the Bz was around ‑15. Crazy.

And the auro­ral oval looked like this. When it’s yel­low, that’s usu­al­ly a good sign. Red—that much red—is flat-out amazing.
