Right now
The most recent data we hold from SPC arrived 4 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
13 other detections within 20 km in the last 24 hours, the nearest <1 km from here.
Reported by SPC today.
It is the 4th strongest of the 49 detections recorded within 20 km of this point since 2 April 2026. Another comparable one was recorded here earlier the same day. 11 more were recorded here in the fortnight before it.
