Right now
The most recent data we hold from NOAA arrived 6 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 11 July 2026 at 01:30 UTC. It is kept here as a record.
No stronger detection stands among the 34 recorded within 20 km of this point since 16 March 2026 — 12 others scored the same. The last comparable one was on 10 July 2026. 4 more were recorded here in the fortnight before it.
