Right now

The most recent data we hold from SPC arrived 26 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.

28 other detections within 20 km in the last 24 hours, the nearest 7 km from here.

Reported by SPC 94 days ago.

It is the 12th strongest of the 101 detections recorded within 20 km of this point since 16 March 2026. The last comparable one was on 25 May 2026. 4 more were recorded here in the fortnight before it.
