Right now
The most recent data we hold from NOAA arrived 66 minutes 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.
This alert expired on 1 July 2026 at 20:00 UTC. It is kept here as a record.
It is the 17th strongest of the 130 detections recorded within 20 km of this point since 10 March 2026. Another comparable one was recorded here earlier the same day. 4 more were recorded here in the fortnight before it.

How we know
19 recorded sources include NOAA; independence is not established by this count.
Our own score for this event is 22 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.
