Right now
The most recent data we hold from NOAA arrived 54 minutes 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.
This alert expired on 14 June 2026 at 22:15 UTC. It is kept here as a record.
No stronger detection stands among the 79 recorded within 20 km of this point since 17 March 2026 — 15 others scored the same. Another comparable one was recorded here earlier the same day. 6 more were recorded here in the fortnight before it.

How we know
One source: NOAA. Not yet confirmed by a second, independent source.
Our own score for this event is 46 out of 100.
