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.
2 other detections within 20 km in the last 24 hours, the nearest <1 km from here.
This alert expired on 19 May 2026 at 01:00 UTC. It is kept here as a record.
No stronger detection stands among the 306 recorded within 20 km of this point since 10 March 2026 — 77 others scored the same. Another comparable one was recorded here earlier the same day. 52 more were recorded here in the fortnight before it.
