Abstract

On 16 January 2025, an occultation of the star UCAC4 644-038283 (Gaia DR3 ID 944967984227916160) by the main-belt asteroid (709) Fringilla revealed the previously unknown binarity of this star. The distance between the two components was determined to be 0.0331" ± 0.0004", the position angle results in 63.3° ± 1.6°.
