Right now
The most recent data we hold from NOAA arrived 3 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 14 May 2026 at 05:30 UTC. It is kept here as a record.
It is the 2nd strongest of the 118 detections recorded within 20 km of this point since 8 March 2026. The last comparable one was on 13 May 2026. 61 more were recorded here in the fortnight before it.
