Observer
NameAdam B
Experience Level4/5
RemarksImmediately after observation I pulled out my smartphone and noted the time. Together with another observer (Sarah Pallo, 602-300-1563), we determined the location of the fireball compared the night sky. The observation started in the vicinity of Castor and moved diagonally to Kocab before fragmenting into 4-5 pieces, finally disappearing behind trees below 10 degrees in altitude.
