I was going to skip today, but I finally got my iPhone and my iMac talking to each other and managed to download some photos. Yesterday the sky was spectacular and I didn’t have my camera with me. I can’t see the screen of my iPhone in bright light (same is true of my camera) so this was basically point it at the right part of the sky and guess where the trigger (also on screen) was.
The sky was unusual in that there was a retreating edge of cloud to the north, which I couldn’t quite figure out. The evening weather show made it clear: there was a strong spiral low in the Gulf of Alaska to the south, and the blue sky was a clear air sector between two cloud bands. The spiral was turning in such a direction that the clear band moved over us from south to north. The photo was taken looking east, and the clouds thickened to opacity just to the left of the photo.
