Reports Report 638aa (Event 638-2015)

Name Christopher S
Experience Level 4/5
Remarks At first I thought this was a low flying jet over Loveland, CO. It appeared VERY low flying directly west toward the mountains. Until I saw the head of the fireball (glowing a light green, almost a magnesium type burn) I realized what I was watching. The altitude appeared very low and the angle was flat (hence the initial reaction this was an aircraft). The fireball faded as it approached the foothills. I did not witness any flashes or impact, but from my point of view it would not have made it over mountains.
