Reports Report 638du (Event 638-2015)

Observer
Name Phil T
Experience Level 3/5
Remarks I have never seen anything like this and would not have have bother to report what 2 of us saw if I didn't think it was important and wanted to know what it was.. For a moment I thought it was a fast moving jet on fire. It had a fairly long tail and seemed to disappear in the direct of the mountains. It probably took 10 to 15 seconds to travel across the sky east to west. What a great experience.
