Right now
The most recent data we hold from NOAA arrived 32 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 September 2026 at 00:00 UTC. It is kept here as a record.
No stronger detection stands among the 79 recorded within 20 km of this point since 23 April 2026 — 10 others scored the same. Another comparable one was recorded here earlier the same day.

How we know
3 recorded sources include NOAA; independence is not established by this count.
Our own score for this event is 28 out of 100.
