CBET 5103 : COMET C/2022 B4 (BOK) An apparently asteroidal that was reported on CCD images taken on Jan. 29 UT by H. Groeller with the 2.25-m Bok reflector at Kitt Peak as part of a survey collaboration with the Catalina Sky Survey, Spacewatch, and the University of Minnesota (termed the "Bok NEO Survey") has been found by CCD astrometrists elsewhere to show cometary appearance. The comet, whose discovery observations are tabulated below, has been designated C/2022 B4 after the designation "B3" was given to a very unusual, apparently asteroidal object with a nearly parabolic retrograde short-period orbit (A/2022 B3; cf. MPEC 2022-D24). T = 2022 Jan. 29.89686 TT Peri. = 152.95630 e = 0.9964106 Node = 340.66160 2000.0 q = 1.3796528 AU Incl. = 20.04378 H = 20.0 and 2.5n = 8 |
