Reports Report 638gb (Event 638-2015)

Observer
Name Matthew B
Experience Level 4/5
Remarks The apparent speed of the object was slower than a normal meteor, but faster than an airplane. I estimated it as 1000 mph at 5 miles range, but without knowing its true range these numbers are likely well off the mark.
