Right now

The most recent data we hold from USGS arrived 7 hours ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.

Nothing else has been detected within 20 km in the last 24 hours.

Reported by USGS 61 days ago.

It is the strongest of the 8 detections recorded within 20 km of this point since 20 March 2026. The last comparable one was on 12 July 2026. One more was recorded here in the fortnight before it.

How we know

2 recorded sources include USGS; independence is not established by this count.

Our own score for this event is 20 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.
