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.

One other detection within 20 km in the last 24 hours, 13 km from here.

This alert expired on 4 July 2026 at 20:45 UTC. It is kept here as a record.

No stronger detection stands among the 10 recorded within 20 km of this point since 27 April 2026 — 2 others scored the same. Another comparable one was recorded here earlier the same day. 2 more were recorded here in the fortnight before it.
