Reports Report 5113aq (Event 5113-2017)

Name Christy P
Experience Level 2/5
Remarks I was inside, and therefore couldn't identify any sounds. From where I was standing, it appeared to come almost straight down, slightly to the west. The building I was in had an entirely glass wall, 2 stories high, through which I saw the object, but it's descent was obscured by the high-rises in Denver (which we are pretty close to) - which accounts for the short distances reported between what angle I first observed it, and what angle I stopped observing it. Please note that the time is approximate - I didn't actually verify the time when I saw it. Unlike the more common meteor shower 'shooting stars', this appeared very large and slow and the difference in color of the main object and it's trail was perceptible (birght green object versus a yellow-golden trail). Remarkable.

Remarks There was an extremely bright (similar brightness to the 'ball' itself) yellow, sparkly tail trailing directly with the object. I assume the'sparkles' were fragmenting pieces, none of these were that large since they didn't 'tail' themselves....
