Reports Report 1550o (Event 1550-2015)

Observer
Name Kathleen H
Experience Level 3/5
Remarks This was the second event I observed. It was 12 minutes after the first and was seen close to where the first sighting had disappeared. There was a cloud cover with no stars visible. It was straight ahead in my line of vision, moved very rapidly from right to left behind trees, then seemed to zip back and forth, but ended to the left growing to the size of a full moon, flashed and disappeared.
