Right now

The most recent data we hold from USGS arrived 3 hours ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.

One other detection within 20 km in the last 24 hours, 11 km from here.

Reported by USGS 56 days ago.

It is the 6th strongest of the 15 detections recorded within 20 km of this point since 19 March 2026. The last comparable one was on 15 July 2026. One more was recorded here in the fortnight before it.
