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 6 June 2026 at 05:45 UTC. It is kept here as a record.
It is the 20th strongest of the 59 detections recorded within 20 km of this point since 16 March 2026. Another comparable one was recorded here earlier the same day. 8 more were recorded here in the fortnight before it.

One source: NOAA. Not yet confirmed by a second, independent source.
Our own score for this event is 22 out of 100, at 61 % confidence.
