Right now

The most recent data we hold from NOAA arrived 4 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 July 2026 at 00:02 UTC. It is kept here as a record.

No stronger detection stands among the 16 recorded within 20 km of this point since 10 May 2026 — 6 others scored the same. Another comparable one was recorded here earlier the same day. 4 more were recorded here in the fortnight before it.
