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

This alert expired on 18 May 2026 at 20:00 UTC. It is kept here as a record.

No stronger detection stands among the 60 recorded within 20 km of this point since 15 March 2026 — 13 others scored the same. Another comparable one was recorded here earlier the same day. 14 more were recorded here in the fortnight before it.
