The Object by the Calbuco Eruption
In 22 to 23 April 2015, near Calbuco volcano, southern Chile, a pair of white lights, or a single bright object, hovering near the giant ash column before disappearing. This case file covers what witnesses reported, the official narrative, and a two-pass assessment with its evidence tier.
What did witnesses see at Calbuco volcano?
A pair of white lights, or a single bright object, hovering near the giant ash column before disappearing.
More footage and images of this sighting

What is the official explanation?
No statement on the object. A UFO researcher assessed it as a DJI Phantom 2 quadcopter from the four-light hover pattern; a Chilean network suggested a helicopter and reported a pilot mistaken for a UFO.
What did the witnesses think it was?
Uploaders and viewers presented it as a UFO drawn to the eruption.
The dispute
The dispute is that the object filmed near the Calbuco eruption column on 22-23 April 2015, presented by uploaders and viewers as a UFO drawn to the volcano, is almost certainly an ordinary aircraft caught against a dramatic backdrop. The footage shows a pair of white lights, or a single bright object, hovering near the giant ash column before disappearing. No official agency issued any statement on the object itself, so the counter-explanation here is a civilian one with a stated method, not an apparatus assertion.
The strongest counter-explanation is a specific identification: a UFO researcher assessed the object as a DJI Phantom 2 quadcopter, reading it from the four-light hover pattern visible in the video. This is a method-shown debunk rather than a bare claim, the four-light signature is a concrete, checkable feature of that drone model rather than a hand-wave, and it fits what the footage actually shows. A separate prosaic explanation also exists: a Chilean network suggested a helicopter and reported a pilot who was mistaken for a UFO. Both of these are prosaic readings that come with a method and fit the visual evidence well.
What keeps this from being formally closed is that the two prosaic explanations compete rather than converge on a single confirmed object, and no party produced an independently verified identification of the exact craft. The archive therefore lists the case as Disputed, meaning a counter-explanation exists but does not, on the record, fully settle it. Still, the dramatic eruption backdrop inflates the impression more than the object supports, and a specific drone model identified from a demonstrable light pattern is the kind of method-backed explanation that comes close to settling the sighting as ordinary technology rather than anything anomalous.
Is the Object by the Calbuco Eruption real? The two-pass assessment
The drone and helicopter explanations both show a method and fit well, so this leans prosaic. The dramatic backdrop inflates the impression more than the object supports.
