Right now
The most recent data we hold from NOAA arrived 5 hours 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 11 June 2026 at 00:00 UTC. It is kept here as a record.
It is the 126th strongest of the 251 detections recorded within 20 km of this point since 16 March 2026. Another comparable one was recorded here earlier the same day. One more was recorded here in the fortnight before it.
