Right now
The most recent data we hold from NOAA arrived 14 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 2 July 2026 at 01:00 UTC. It is kept here as a record.
It is the 59th strongest of the 93 detections recorded within 20 km of this point since 9 March 2026. The last comparable one was on 22 June 2026. 16 more were recorded here in the fortnight before it.

How we know
2 recorded sources include NOAA; independence is not established by this count.
Our own score for this event is 39 out of 100.
