This alert expired on 16 March 2026 at 23:00 UTC. It is kept here as a record.

No stronger detection stands among the 161 recorded within 20 km of this point since 16 March 2026 — one other scored the same. Another comparable one was recorded here earlier the same day. One more was recorded here in the fortnight before it.
