Right now
The most recent data we hold from GDACS arrived 88 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, <1 km from here.
Reported by GDACS today.
It is one of only 2 we have recorded within 20 km of this point since 18 September 2026. Another comparable one was recorded here earlier the same day. One more was recorded here in the fortnight before it.

How we know
2 recorded sources include GDACS; independence is not established by this count.
Our own score for this event is 11 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 v5. Rows carrying other versions were judged by different rules and are not directly comparable.
