Reports Report 1570i (Event 1570-2014)

Observer
Name Tony R
Experience Level 1/5
Remarks At first I thought it was a firework, then realized the trajectory was wrong (was not going up but across the sky) and there was no sound with the streak. It was also blue in color and very bright, especially towards the end when the whole sky lit up with a big burnout. It was at least 30-60 seconds after it disappeared before I heard what sounded like an explosion (like maybe it had hit the ground or a delayed sonic boom?)
