This asteroid was discovered to be a binary asteroid by me and Jean-Francois Gout Nov 16-20 of 2024. We dont have an orbit yet, but the orbital period is 23.2 hours, The asteroids are only 1.9 km in diameter and gravity is weak, my calculation shows the minimu semi-major axis is 17 km, so there's certainly a chance for missing both of them. Duration this time is only 0.3 seconds and not 0.52 s as it was last November. So each component will be even less. Will required good conditions to get good data. Fortunately, only a 17% moon and not in the picture so seeking dark skies will help.

Alt=32, Az=274 in Taurus.
