This report has been linked to the following event: Event 638-2015
Observer
NameKirkpatrick J
Experience Level3/5
RemarksVery large, not just a point of light. For several seconds it appeared to have greenish flame at the trailing end. Could not determine shape, but did not seem to be "round" or "oblong". Can't say rectangular, but it somehow had the appearance of "edges", but too bright to really determine that. Seemed more like a box and was traveling so slowly it had the sensation of "drag" to it. When I heard that folks in Wyoming had seen it I was surprised. Seemed to me that it was going over Longmont and traveling somewhat south from there, but very had to judge of course. Would be surprised if it cleared the mountains, but there again difficult to judge. Thank you.
