Right now
The most recent data we hold from NOAA arrived 32 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
Nothing else has been detected within 20 km in the last 24 hours.
This alert expired on 16 March 2026 at 08:30 UTC. It is kept here as a record.
It is the 22nd strongest of the 34 detections recorded within 20 km of this point since 16 March 2026.
