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.
One other detection within 20 km in the last 24 hours, 16 km from here.
This alert expired on 7 September 2026 at 20:45 UTC. It is kept here as a record.
It is one of only 4 we have recorded within 20 km of this point since 18 June 2026. Another comparable one was recorded here earlier the same day.
