| Persistent train | |
|---|---|
| Observation | Yes |
| Duration | 1s |
| Length | -1° |
| Remarks | Thin glowing train, with little to no smoke, but that produce a few sparks like a sparkler. perspective-wise, the train had about the length equivalent to the height of the National Agricultural Library building (14-story building), which I could see in front of me while I was driving. |
| Terminal flash | |
|---|---|
| Observation | Yes |
| Remarks | The terminal flash lasted a second or less, and it was very bright (almost like a camera flash or a welding torch), appearing white at the center, but yellowish or orange-ish around the edges (note that this happened on a sunny day, with almost no clouds, at around 1PM, and I was waring classes that get darker in the sunlight). There were a few bright fragments or sparks in the train and around the fireball. Within a second or two after the flash, all signs of the meteor had vanished like a vapor. The fireball appeared to begin the terminal flash at a height relative to about the top of the National Agricultural Library building (14 story building) and ended below the mid-point relative to the same building (maybe about the 5th floor). My vantage point was that I was driving eastbound on I495, and the National Agricultural Library building right in front of my field of view. |
