This report has been linked to the following event: Event 451-2015
Observer
NameMatthew D
Experience Level2/5
RemarksAt first I thought it could be a plane as local air traffic follows a similar line from my vantage point but it was clearly an object breaking apart and burning. The residual trails of fire were quite long- both in space and duration of visibility. On a personal note: it was by far the coolest shooting star I've ever seen!

Fragmentation
ObservationYes
RemarksBroke into approximately 10 segments. Each left a long semi-horizontal comet-like trail. There was one vertical fragment that fell a few seconds after the main segment disappeared below the horizon (behind a local butte); it appeared in approximately the area of the origin of visibility. The main segment seemed large enough that it might actually make contact to Earth surface but no residual sound effects could be heard from my location within 15 seconds after object was no longer in sight.
