Right now
The most recent data we hold from NOAA arrived 14 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 15 June 2026 at 03:00 UTC. It is kept here as a record.
It is the 56th strongest of the 250 detections recorded within 20 km of this point since 16 March 2026. The last comparable one was on 10 June 2026. One more was recorded here in the fortnight before it.
