Observing geometry of FA22 relative to the Moon and Earth in the projected ecliptic x–y (left) and x–z (right) planes. The stars mark the first observation on each date listed in Table A.1. The vertical bar indicates the projected point at the closest Earth approach (2025-09-18 at 07:39:48.108 UTC; distance ≈842 060 km). The solid black arrow indicates the anti-solar vector at the median epoch of the observing campaign.
