Reports Report 454av (Event 454-2017)

Name larry a
Experience Level 3/5
Remarks I was seated in my office and DID NOT see the actual fireball, but the door is completely made of unrestricted glass and is large. I could see the intense flash of which there was a shimmering effect you could clearly see off the roofs of homes. It was nearly if not as bright as the Sun and This was by no means average. I could not visibly see any contrail, smoke etcetera. I wish I could give an accurate or viable trajectory but it would just be guessing. What was odd is that the intense brightness gave no "path" or trajectory. As if this anomaly was quite large.
