Reports Report 667ew (Event 667-2013)

Observer
Name Michael K
Experience Level 3/5
Remarks I've never seen anything like this. It was low on the horizon, appeared to have a long tail, and we observed it for up to 10 seconds before it flamed out in a flash. At first I thought it was a flare or firework, but it traveled at a constant speed and remained parallel to the horizon. My son and I corroborated our stories as we watched.
