Right now

The most recent data we hold from NOAA arrived 1 minute 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 4 July 2026 at 01:22 UTC. It is kept here as a record.

It is the 12th strongest of the 26 detections recorded within 20 km of this point since 17 March 2026. Another comparable one was recorded here earlier the same day. 5 more were recorded here in the fortnight before it.

How we know

11 recorded sources include NOAA; independence is not established by this count.

Our own score for this event is 43 out of 100.

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