SOHO Camera Catches Giant UFO Shooting Past With Fury Of A Thousand Rockets, Aug 4, 2015, UFO Sighting News.

Date of sighting: August 4, 2015 at 7:00
Location of sighting: Earths sun
Camera: SOHO LASCO C2 

This UFO is seen at the 5 second mark in the video. This video was posted by NASA and is one of their Youtube channels. The UFO is moving at incredible fast. The photo just before it taken at 6:48 shows nothing, but at 7:00 bam! It has already shot across the sun. Not even a comet could be capable of such speed. It would take hours and even day for a comet to do this. The UFO is the small white dot ahead of the fiery trail. 

This trail is very similar to the Russian and American Rocket trails made. Its much slower than light speed, but still mind boggling.
