Right now

The most recent data we hold from EMSC arrived 44 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.

Nothing else has been detected within 20 km in the last 24 hours.

It is one of only 3 we have recorded within 20 km of this point since 10 May 2026. Another comparable one was recorded here earlier the same day. One more was recorded here in the fortnight before it.
