What should you do when you see a UFO?
First, you should call for other people to come and watch the UFO with you. The more witnesses, the more credible the report will be to investigators. Second, you should observe very carefully. If you have a camera, take pictures of the UFO that include known objects in the foreground and background.
Remember as many details as possible, especially the time, date, duration, and location of the sighting, the UFO's appearance, shape, apparent size and distance, lights, colors, direction, estimated speed, trajectory, motions, actions, sounds, and how you lost sight of it. Third, after the sighting ends, write down as many details as you can remember. Draw a sketch of the UFO (even if you took photographs) and a map of the area where the sighting occurred.
If the UFO left any physical traces or effects, protect the evidence so researchers can investigate and analyze it. Finally, and most importantly, contact the Center for UFO Studies to file your report.
