Reports Report 3434arm (Event 3434-2013)

Observer
Name Richey P
Experience Level 3/5
Remarks I have seen many shooting stars/meteor showers (and Halley''s Comet) over 40 years; this was a much brighter object with a much longer duration than anything I have seen before. It was a bright white to very pale green at first. It was a little bigger and brighter than any planets I've seen. Duration was at least 30 seconds; I equate it somewhat with the speed of the space station passing over, maybe slower. I was driving & initially caught the fireball out of the corner of my eye. I stopped immediately and turned to look to the east. It was coming from ESE. It was a little ways above the tree line and had only a hint of a tail. I thought for a second that someone was shooting off a Roman candle except that there was only one fireball and it was moving horizontally. The fireball continued in an almost horizontal trajectory moving NW, in a very, very slight downward arc, if at all. I drove a short distance, 3 houses maybe, to the stop sign at Sherman Blvd & Madison. From there I watched the fireball until it was due North, where it had become a much more intense light green. The fireball then flashed slightly, and 2 or three sparks flew off, disappearing next to the fireball which also disappeared. There was no sound that I noted; I had rolled down my car window when I first saw the fireball.
