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.
34 other detections within 20 km in the last 24 hours, the nearest 4 km from here.
This alert expired on 11 June 2026 at 23:30 UTC. It is kept here as a record.
No stronger detection stands among the 300 recorded within 20 km of this point since 16 March 2026 — 8 others scored the same. Another comparable one was recorded here earlier the same day. 7 more were recorded here in the fortnight before it.
