This report has been linked to the following event: Event 511-2019
Observer
NameMATTHEW F
Experience Level5/5
RemarksI have a degree in Physics and a minor in Astronomy. I have only seen one other fireball in my life. This one was so unusual because of the cobalt blue color which oscillated with some green glow as well. My initial thought was that it was a firework, but the velocity of the event and my relative perspective put this in the meteor / satellite re-entry category for me. Very bright and cast a shadow for a second or two.
