Reports Report 4174a (Event 4174-2017)
| Observer | |
|---|---|
| Name | Aaron V |
| Experience Level | 3/5 |
| Remarks | The object was large and extremely fast. Covering a large portion of the night sky very quickly. This is by far the biggest meteorite I have ever seen. With the distance traveled being the longest as well as the width of the trail. It is also the only green one I have seen. BRIGHT GREEN. A friend of mine also saw a bright green fireball that was bigger than this in the Phx, AZ area a month before mine. He told me about his experience a few days before this happened to me, which is why I thought it was so bizarre...2 green fireballs in the same city, within a month. |
