Right now
The most recent data we hold from EMSC arrived 5 minutes 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, 19 km from here.
Reported by EMSC today.
It is one of only 3 we have recorded within 20 km of this point since 22 June 2026. The last comparable one was on 24 September 2026. One more was recorded here in the fortnight before it.
