Right now
The most recent data we hold from NOAA arrived 34 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 June 2026 at 09:15 UTC. It is kept here as a record.
It is the 6th strongest of the 42 detections recorded within 20 km of this point since 12 March 2026. Another comparable one was recorded here earlier the same day. 8 more were recorded here in the fortnight before it.
