Right now
The most recent data we hold from NOAA arrived 3 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 4 July 2026 at 00:50 UTC. It is kept here as a record.
No stronger detection stands among the 82 recorded within 20 km of this point since 9 April 2026 — 15 others scored the same. Another comparable one was recorded here earlier the same day. 18 more were recorded here in the fortnight before it.

Our own score for this event is 46 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.
