On Confirmed and Suspected Binary Asteroids Observed at the Center for Solar System Studies

The analysis of observations made at the Center for Solar System Studies from 2020 July through September, led to the discovery or confirmation of two binary asteroids: the Vestoid 4030 Archenhold and NEA (85275) 1994 LY. The latter had been reported as a suspected binary by Pravec et al. (2007web). An additional nine asteroids were found to have a secondary period but without confirming mutual events (occultations/eclipses) due to a satellite: the known Hungaria binary 2577 Litva, 5928 Pindarus (Hilda), 7174 Semois (Hilda), (16970) 1998 VV2 (Hilda), (39282) 2001 BM36 (Hilda), (119356) 2001 SF235 (inner main-belt), (159402) 1999 AP10 (NEA), (420302) 2011 XZ1 (NEA), and 2019 AN5 (NEA). We discuss the likelihood of eight of those objects actually being binary.
