Date of sighting: Oct 12, 2016
Location of sighting: Colima Volcano, Mexico
This large disk was seen by Streetcap1 of Youtube. He noticed it as it was coming out of the side of Colima Volcano this week. Its that that several ancient volcanos in Mexico hide underground base for alien and the exits are in the mouth, but when the volcano is active like today, all ships exit the sides of the volcano.

This is the third one I have seen, I dare say there are others. This one appears quite slow but larger than the previous two.
