Right now
The most recent data we hold from USGS arrived 49 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
One other detection within 20 km in the last 24 hours, 11 km from here.
Reported by USGS 48 days ago.
It is the 7th strongest of the 80 detections recorded within 20 km of this point since 12 March 2026. The last comparable one was on 26 July 2026. 20 more were recorded here in the fortnight before it.

How we know
One source: USGS. Not yet confirmed by a second, independent source.
Our own score for this event is 0 out of 100.
This is our versioned heuristic index, not source severity or a calibrated probability. Urban PEI does not count unique people.
Computed under scoring rules v1. Rows carrying other versions were judged by different rules and are not directly comparable.
