Right now

The most recent data we hold from NOAA arrived 10 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 6 June 2026 at 22:00 UTC. It is kept here as a record.

It is the 2nd strongest of the 5 detections recorded within 20 km of this point since 24 May 2026. The last comparable one was on 24 May 2026. One more was recorded here in the fortnight before it.
