The most recent data we hold from NOAA arrived 2 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 10 May 2026 at 01:15 UTC. It is kept here as a record.
No stronger detection stands among the 14 recorded within 20 km of this point since 10 May 2026 — 11 others scored the same. Another comparable one was recorded here earlier the same day. 7 more were recorded here in the fortnight before it.

How we know
Confirmed by 21 independent sources, including NOAA.
Our own score for this event is 22 out of 100, at 70 % confidence.
