Right now
The most recent data we hold from NOAA arrived 12 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 <1 km from here.
This alert expired on 10 June 2026 at 18:15 UTC. It is kept here as a record.
It is the 2nd strongest of the 47 detections recorded within 20 km of this point since 10 March 2026. Another comparable one was recorded here earlier the same day. 2 more were recorded here in the fortnight before it.
