This hand-held iPhone image shows the view from 39 N latitude at 9:38 PM on 11/11/2025. The edge of the aurora (or possibly a SAR) reaches all the way to due east. Orion can be seen rising on the right as its reflection sets into the lake. #astrophotography

After the outburst ended after 9:00, this Unchanging Red Band stayed in the sky until the midnight outburst. It's not an aurora, it is a Stable Auroral Red arc (SAR). They were named before we knew how they formed. I propose we call them URB spaceweatherarchive.com/2021/11/22/3... #astrophotography

A cropped still from the after midnight outburst shows the reflected aurora better as the lake was calmer, more lights have been turned off, and the red pillars were closer to the horizon. The Big Dipper shines through in the center. #astrophotography

There was another outburst after the moon rose after midnight. I didn't see this one, but my camera did! 98x time-lapse, Sony Alpha 7 III, FE 14 mm f/1.8 lens, ISO 1250, 4s exposures. #astrophotography

I was not paying much attention to the aurora alerts as it was supposed to be cloudy last night. I set up my camera after noticing the clouds were glowing red at 6:30 PM. They move out like a curtain rising just before the show starts! 98x time-lapse staring at 6:45 PM. #astrophotography

Well at least the aurora is making our clouds colorful. Hoping for some clearing in a couple of hours.

A Sharon Begley byline, almost 5 years after her death.
Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."
Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.

On the event of James Watson's death, I highly recommend this 2023 commentary from @matthewcobb.bsky.social and Nathaniel Comfort with crucial new insights into the discovery of the double helix. (And also check out Cobb's brand new biography of Francis Crick) www.nature.com/articles/d41...
What Rosalind Franklin truly contributed to the discovery of DNA’s structure
Franklin was no victim in how the DNA double helix was solved. An overlooked letter and an unpublished news article, both written in 1953, reveal that she was an equal player.
