Name | Christopher S |
Experience Level | 4/5 |
Remarks | The sky was about 80% totally clear and 20% high hazy clouds to the west, well away from the sighting. It was dusk, and it was still light enough to see color faintly on the parked cars. I was speaking to another man working on his racecar at the time, so I wasn't paying attention to the sky, but I sort of noticed something different had happened to the ambient lighting of the sky (perhaps the meteor was much brighter as it passed overhead) and, with a small delay, looked up to the east, noticing the very green meteor for the first time. As I followed it, it flashed four times distinctly, disappearing after the final one. With difficulty due to the still fairly light sky, I located Polaris, the north star, and estimated the azimuth of the sighting relative to that star. The sky was too bright for me to identify the constellations through which the meteor passed. I suspect the meteor would have looked much more spectacular if the skies were truly nighttime dark, and I would have seen it sooner and observed it over more of its flight. |

Observation | Yes |
Remarks | I heard, about ten to fifteen minutes (didn't check the exact time) after the sighting, a very muffled and faint sonic boom-like sound from straight overhead. I hadn't seen the meteor from the start so it may have passed overhead--it was still partly light out and I was talking to someone at the time, so I only saw the meteor near the end of its flight, so I'm not sure if the sound was from the meteor or not. It was very quiet at the racetrack where the sighting took place (no events--was just preparing my kids' cars for new numbers in the parking area). |

Observation | Yes |
Remarks | At several points, about 35°, 25°, and 20° above the ENE horizon the meteor appeared to vanish from sight, then suddenly flash back to full brilliance, the final visible flash being about 15° above the ENE horizon. |
