Right now
The most recent data we hold from NOAA arrived 5 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
5 other detections within 20 km in the last 24 hours, the nearest 2 km from here.
This alert expired on 24 September 2026 at 01:45 UTC. It is kept here as a record.
It is the 8th strongest of the 44 detections recorded within 20 km of this point since 11 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
One source: NOAA. Not yet confirmed by a second, independent source.
Our own score for this event is 16 out of 100.
