Right now

The most recent data we hold from NOAA arrived 4 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 23 June 2026 at 01:45 UTC. It is kept here as a record.

It is the 63rd strongest of the 109 detections recorded within 20 km of this point since 17 March 2026. Another comparable one was recorded here earlier the same day. One more was recorded here in the fortnight before it.
