(7763) Crabeels (1990 UT5,1994 RE1) A mid-main belt asteroid imaged on the first night of the 2022 November talcos. When we photographed comet C/2021 Y1 (ATLAS), this was included in the pictures. The asteroid was discovered by Belgian astronomer Eric Walter Elst at the ESO La Silla Observatory (809 European Southern Observatory, La Silla) on 16 October 1990. Elst has found a total of 3868 asteroids and comet/asteroid 7968 Elst-Pizarro. Source Wikipedia https://en.wikipedia.org/wiki/Eric_Walter_Elst . The asteroid got its name from the Dutch, Antwerp organist Henri Crabeels (b. 1904). The size of the asteroid is 7.79 km. Spectral class spec_B=>L . When photographing, the asteroid was at a distance of 1.9000au and at its closest on November 29, 2022 at 1.887au.
