Anyone check eam.watch for skykings near that time frame?
Nevermind, doesn't appear to have any correlation.

Greg Johnson of Skunk Bay Weather was looking through the pictures snapped by a weather camera on the Kitsap Peninsula when he spotted a photo with a mysterious object. The picture - snapped at 3:56 a.m. Sunday by a high-quality, 20-second exposure camera - shows a bright orange streak in the early morning sky over Whidbey Island.
Johnson told Q13 News he was hesitant to release the photo.
Mostly, because it appears to be a missile launched from Naval Air Station Whidbey Island.
So, that explains the ridiculously long exhaust, a 20-second time-lapse photograph.
