The sky was amazing this morning. The sunrise created the most unusual blues with white clouds that turned magenta then orange. Surprisingly, I turned around and saw a rainbow begin for form from left to right with a bright blue sky behind it (looking north and west). I fumbled for my Note 9 cell phone and could not capture the rainbow with one image, so I moved my phone vertically, shifted to pano mode and captured this. My house is at the bottom of the hill in Danville, California.
