Right now

The most recent data we hold from SPC arrived 12 hours ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.

Nothing else has been detected within 20 km in the last 24 hours.

Reported by SPC yesterday.

No stronger detection stands among the 103 recorded within 20 km of this point since 25 April 2026 — 74 others scored the same. Another comparable one was recorded here earlier the same day. 59 more were recorded here in the fortnight before it.
