Right now
The most recent data we hold from NOAA arrived 53 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 17 May 2026 at 01:00 UTC. It is kept here as a record.
It is the 101st strongest of the 131 detections recorded within 20 km of this point since 15 March 2026. Another comparable one was recorded here earlier the same day. 2 more were recorded here in the fortnight before it.

How we know
10 recorded sources include NOAA; independence is not established by this count.
Our own score for this event is 34 out of 100.
