Right now
The most recent data we hold from NOAA arrived 7 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, 20 km from here.
This alert expired on 3 July 2026 at 23:49 UTC. It is kept here as a record.
It is the 12th strongest of the 70 detections recorded within 20 km of this point since 12 June 2026. Another comparable one was recorded here earlier the same day. 15 more were recorded here in the fortnight before it.
