How to describe a sighting
Techniques & investigation methods
A good report gives the date, exact time, place, direction and elevation, duration, color, shape, movement, weather conditions, what remains of the observation (photos, videos) and other witnesses. It separates what was seen from what is assumed. The more precise it is, the more likely it is to be explained or to remain useful.
