Sharing all 1689 photos from 1126pm to 1234am last night with no editing. I started out with 5 second exposures. As the aurora brightened and sped up I lowered, eventually getting to 1 second exposures at 43 seconds in to this video.
It was the best show I’ve seen in a few years. This video is normal speed and how it appeared to me (and except smoother and more detailed in real life). Part way through I increased my shutter speed (gets darker) because it wasn’t keeping up.
Olga Semydyanova, a mother of 6 children, was killed in a battle against #russian bastards.
She expressed a desire to defend the country to the end, even when she knew that their battalion might not survive.
She is a hero of #Ukraine. She is my hero.

three specimens, presumed to be natural hybrids analyzed in this study were identified as interspecific hybrids between female R. notatus and male R. ocellatus.
The suggested prediction model showed good agreement with the steam/water experimental results, and it can be extended to predict the steam/water two-phase pressure drop for moisture separators.
