Right now
The most recent data we hold from NOAA arrived 12 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 30 June 2026 at 04:30 UTC. It is kept here as a record.
No stronger detection stands among the 140 recorded within 20 km of this point since 3 April 2026 — 93 others scored the same. Another comparable one was recorded here earlier the same day. One more was recorded here in the fortnight before it.
