Bright blue flashes (flashed twice like lightning) lit up the Barrow sky. Viewed out my window but I only seen the whole sky light up.Facebook Posts:Another witness said it was blue with orange sparkles as it zoomed above Barrow towards Wainwright. People wondering what it was and were talking about it on their VHF's in Wainwright (village about 60 miles west of Barrow).Another witness seen 2 planes flying north of Barrow during the same time.Another person said he thought someone was taking pictures outside, turned out the whole sky lit up and seen the flashes on the houses and snow/ground all around.
