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 18 May 2026 at 03:15 UTC. It is kept here as a record.

It is the 18th strongest of the 30 detections recorded within 20 km of this point since 16 March 2026. Another comparable one was recorded here earlier the same day. 8 more were recorded here in the fortnight before it.
