Right now
The most recent data we hold from SPC arrived 10 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
6 other detections within 20 km in the last 24 hours, the nearest <1 km from here.
Reported by SPC today.
No stronger detection stands among the 17 recorded within 20 km of this point since 16 March 2026 — 5 others scored the same. Another comparable one was recorded here earlier the same day. 4 more were recorded here in the fortnight before it.
