Right now
The most recent data we hold from NOAA arrived 6 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 22 June 2026 at 23:30 UTC. It is kept here as a record.
It is the 2nd strongest of the 89 detections recorded within 20 km of this point since 5 May 2026. Another comparable one was recorded here earlier the same day. 8 more were recorded here in the fortnight before it.

How we know
7 recorded sources include NOAA; independence is not established by this count.
Our own score for this event is 22 out of 100.

Computed under scoring rules v1. Rows carrying other versions were judged by different rules and are not directly comparable.
