Right now

The most recent data we hold from NOAA arrived 5 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 23 June 2026 at 22:00 UTC. It is kept here as a record.

No stronger detection stands among the 52 recorded within 20 km of this point since 16 March 2026 — 28 others scored the same. Another comparable one was recorded here earlier the same day. 9 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.

Computed under scoring rules v1. Rows carrying other versions were judged by different rules and are not directly comparable.
