Right now
The most recent data we hold from NOAA arrived 2 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 8 June 2026 at 23:00 UTC. It is kept here as a record.
It is the 9th strongest of the 34 detections recorded within 20 km of this point since 12 April 2026. The last comparable one was on 31 May 2026. 4 more were recorded here in the fortnight before it.
