Right now
The most recent data we hold from NOAA arrived 3 hours ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
One other detection within 20 km in the last 24 hours, 19 km from here.
This alert expired on 2 July 2026 at 01:00 UTC. It is kept here as a record.
It is the 3rd strongest of the 11 detections recorded within 20 km of this point since 2 June 2026. Another comparable one was recorded here earlier the same day. 2 more were recorded here in the fortnight before it.
