Right now
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 8 June 2026 at 00:48 UTC. It is kept here as a record.
No stronger detection stands among the 17 recorded within 20 km of this point since 8 April 2026 — 12 others scored the same. Another comparable one was recorded here earlier the same day. 5 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 60 % confidence.
The score is ours, computed from intensity, exposed population and local history — not the source’s.
Computed under scoring rules v1. Rows carrying other versions were judged by different rules and are not directly comparable.
