Right now
The most recent data we hold from NOAA arrived 3 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
Nothing else has been detected within 20 km in the last 24 hours.
This alert expired on 23 May 2026 at 01:30 UTC. It is kept here as a record.
No stronger detection stands among the 15 recorded within 20 km of this point since 27 March 2026 — 2 others scored the same. The last comparable one was on 18 April 2026.
