This alert expired on 7 May 2026 at 04:45 UTC. It is kept here as a record.

No stronger detection stands among the 18 recorded within 20 km of this point since 9 March 2026 — 7 others scored the same. Another comparable one was recorded here earlier the same day. 6 more were recorded here in the fortnight before it.
