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.
7 other detections within 20 km in the last 24 hours, the nearest <1 km from here.
This alert expired on 15 September 2026 at 22:00 UTC. It is kept here as a record.
It is the 8th strongest of the 24 detections recorded within 20 km of this point since 15 May 2026. Another comparable one was recorded here earlier the same day. 6 more were recorded here in the fortnight before it.
