Right now
The most recent data we hold from NOAA arrived 9 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 21 June 2026 at 23:19 UTC. It is kept here as a record.
No stronger detection stands among the 85 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. 12 more were recorded here in the fortnight before it.
