Residents across B.C. and Alberta reported a large slow-moving white shape May 5; leading explanation is SpaceX Falcon 9 exhaust plume from a Vandenberg launch just before 9 p.m. PT.
Key Takeaways
Sightings spanned hundreds of kilometres: Fort St. John, Prince George, Kamloops, Vancouver Island, Nass Valley, and Sherwood Park, Alta., between 10:15-10:30 p.m. PT.
SpaceX Falcon 9 launched from Vandenberg Space Force Base ~9 p.m. PT; rocket plume illuminated at altitude is the primary candidate.
H.R. MacMillan Space Centre director said video looked “controlled” and ruled out meteor or cloud cover, but declined to speculate further.
Expert framing: crowded low-Earth orbit from drones, private satellites, and rockets is making unidentified sightings structurally more common.
A separate apparent meteor over Victoria one week earlier shows B.C. sky activity is genuinely elevated recently.
Hacker News Comment Review
Strong commenter consensus: this is almost certainly a sunlit cloud or rocket exhaust plume catching post-sunset light at altitude, not anything anomalous.
Commenters drew a direct parallel to the 2024 New Jersey drone panic, where most sightings turned out to be ordinary aircraft misidentified in a charged media environment.
Notable Comments
@foxyv: links example image of Falcon 9 plume illuminated post-sunset; classic high-altitude sunlit exhaust signature.
@sandworm101: “Sunrise/sunset. Cloud is still in sunlight. Not a ufo. Just an interesting cloud getting a moment in the spotlight.”
