Large object enters volcano. Remarkable video.

This video was brought to our attention by Mexican UFO expert Jaime Maussan, and it is remarkable. There is no suggestion of hoax in this video taken by a webcam that watches the Popocatepetl volcano. The volcano has been active lately, and threatens a large human population. So what is this object doing? Also, I might add that it strongly resembles glowing bars that have been recorded in Kentucky recently.
