| Name | Tammy H |
| Experience Level | 2/5 |
| Remarks | slow, low burn fizzle pop. Have lived and worked in Alaska and several desert environments with low light pollution for decades. This was the closest experience I've ever had with a fireball. It was so close it almost felt electrical and there was an aspect of smell associated with the experience, leading me to believe at first that it was a firework, but then recognizing that it was indeed a fireball. Hence, I looked online later in the day to confirm and report. I have had astronomy classes and have observed multiple meteorites in my lifetime. This was by far the best. Two other people witnessed it with me. Stellar! |
