Observation Yes
Duration 90s
Length 15°
Remarks Extremely bright, white light lit up my back yard, like a strobe light. Much brighter than moonlight, very similar to a car headlights passing by (which I though it might be, at first). Initial pulse of light, then about 0.5 seconds later, at very bright strobing flash. I was under our a sunscreen shade of our backyard gazebo, I quickly step out from under it and I looked up toward the North and saw the brightly glowing trail heading East to West about 70 degrees altitude. The left side of the trail was brighter and appeared larger, like a long teardrop shape, with a long tail of yellowish light that quickly faded to orange, then red. The length of the trail was about 15 degrees. This was before sunrise (about 20 minutes before), and the remaining trail was white smoke path that was was pointed at both ends, as it was illuminated by the sun\'s rays at that alititude. The smoke trail widened, with the majority of it traveling south, and it turned into a grayish turbulent cloud. The center of the trail appeared to bloom southward faster than the rest, as though the winds were stronger there, and the trail probably lasted at least 90 seconds before it became hard to find after briefly looking away.
Terminal flash
Observation Yes
Remarks The light pulse was in two stages, an initial fast increase in illumination, about 0.5 seconds, followed by an extremely bright pulse that seemed to last about a second.
Fragmentation
Observation No
