Reports Report 650n (Event 650-2012)

Observer
Name Dianna M
Experience Level 1/5
Remarks GAAAAAA! HOW DO I FIND OUT WHAT IT WAS??!! This is the first time I\'ve seen something like this, so I\'m understandably curious. My first thought was that it was perhaps a plane going down (which might also explain the sirens) but there was no burst of light like I would expect with a plane crash.
