Right now
The most recent data we hold from NOAA arrived 1 minute 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 21 September 2026 at 04:30 UTC. It is kept here as a record.
It is the 7th strongest of the 48 detections recorded within 20 km of this point since 6 May 2026. The last comparable one was on 16 August 2026.

How we know
2 recorded sources include NOAA; independence is not established by this count.
Our own score for this event is 40 out of 100.
