Nothing else has been detected within 20 km in the last 24 hours.
This alert expired on 7 August 2026 at 19:45 UTC. It is kept here as a record.
No stronger detection stands among the 101 recorded within 20 km of this point since 17 March 2026 — 35 others scored the same. Another comparable one was recorded here earlier the same day. 10 more were recorded here in the fortnight before it.
