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 29 July 2026 at 02:15 UTC. It is kept here as a record.
It is the 6th strongest of the 265 detections recorded within 20 km of this point since 11 March 2026. Another comparable one was recorded here earlier the same day. 32 more were recorded here in the fortnight before it.
