| Experience Level | 2/5 |
| Remarks | I only took a guess at the time of day for my observation, I was working outside and do not recall the time of day. It seems that the color pattern began as a reddish yellow, and then transitioned into a brighter blueish, then greenish, on to white as it got closer to the horizon. It first appeared as bright as an electrical arc flash. Bright sunny day here, and the flash was very bright. |
