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.
Nothing else has been detected within 20 km in the last 24 hours.
This alert expired on 19 May 2026 at 01:15 UTC. It is kept here as a record.
It is the 16th strongest of the 36 detections recorded within 20 km of this point since 10 April 2026. Another comparable one was recorded here earlier the same day. 5 more were recorded here in the fortnight before it.

How we know
One source: NOAA. Not yet confirmed by a second, independent source.
Our own score for this event is 32 out of 100.
