This alert expired on 10 May 2026 at 02:15 UTC. It is kept here as a record.

No stronger detection stands among the 21 recorded within 20 km of this point since 15 March 2026 — 5 others scored the same. Another comparable one was recorded here earlier the same day. 3 more were recorded here in the fortnight before it.
