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.
7 other detections within 20 km in the last 24 hours, the nearest 15 km from here.
This alert expired on 20 September 2026 at 00:30 UTC. It is kept here as a record.
No stronger detection stands among the 75 recorded within 20 km of this point since 15 March 2026 — 9 others scored the same. Another comparable one was recorded here earlier the same day. 7 more were recorded here in the fortnight before it.
