Date of sighting: July 27, 2011

Location of sighting: Vancouver, British Columbia, Canada

Eyewitness states:

Wednesday's night sky over Vancouver, BC played host to a pulsating UFO that was captured on video during skywatching activities from Burnaby Mountain Park on July 27, 2011. The UFO was detected by a night vision camera and tracked for nearly five minutes as it travelled SE to NW before disappearing behind a stand of trees. During this period, the UFO was first seen being overtaken by a second, faster-moving object before amplifying its luminous output in what veteran skywatchers describe as a "power-up" incident.

While in flight, the UFO performed multiple power-ups, inviting comparison with another object recorded four nights earlier near Vancouver City Hall.
