Right now
The most recent data we hold from NOAA arrived 4 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
36 other detections within 20 km in the last 24 hours, the nearest 15 km from here.
This alert expired on 3 July 2026 at 21:15 UTC. It is kept here as a record.
It is the 7th strongest of the 55 detections recorded within 20 km of this point since 12 March 2026. Another comparable one was recorded here earlier the same day. 5 more were recorded here in the fortnight before it.
