Right now
The most recent data we hold from NOAA arrived 41 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
2 other detections within 20 km in the last 24 hours, the nearest 21 km from here.
This alert expired on 3 July 2026 at 03:30 UTC. It is kept here as a record.
It is the 2nd strongest of the 29 detections recorded within 20 km of this point since 8 April 2026. Another comparable one was recorded here earlier the same day. 8 more were recorded here in the fortnight before it.
