Right now
The most recent data we hold from SPC arrived 11 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
10 other detections within 20 km in the last 24 hours, the nearest <1 km from here.
Reported by SPC 50 days ago.
It is the 6th strongest of the 87 detections recorded within 20 km of this point since 2 April 2026. The last comparable one was on 29 July 2026. 7 more were recorded here in the fortnight before it.
