Right now
The most recent data we hold from NOAA arrived 2 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 20 km from here.
This alert expired on 4 July 2026 at 16:45 UTC. It is kept here as a record.
It is the 4th strongest of the 72 detections recorded within 20 km of this point since 16 March 2026. The last comparable one was on 7 July 2026. 12 more were recorded here in the fortnight before it.
