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

This alert expired on 25 May 2026 at 14:00 UTC. It is kept here as a record.

No stronger detection stands among the 11 recorded within 20 km of this point since 25 May 2026 — 10 others scored the same. Another comparable one was recorded here earlier the same day. 2 more were recorded here in the fortnight before it.
