I think it's good for any Ufologist or UFO enthusiast to know the general classification of Close Encounters with UFO/ET activities.
Close Encounter of the First Kind (Most Common)
This is when you would have a sighting of a UFO or unidentified flying/submersible object. In most cases, it would need to be close enough where you could easily rule out other potential causes of the sighting.
Close Encounter of the Second Kind
This is when you witness an aftermath left behind from a UFO/ET type activity. This could be crop circles, electrical interference, or even mutilation to livestock as some witnesses have reported.
Close Encounter of the Third Kind
This is when you witness an actual extraterrestrial being. You might see this in the UFO if looking at it close enough, outside the UFO if it had landed or crashed.
These classifications are based off the Hynek's Scale. (Read more about Hynek).
There are also extensions for the 4th kind (being abducted by ET) and the 5th kind (being injured or healed during abduction).
