PKS 0422+004
T. D. Kinman, Kitt Peak National Observatory, suggests that
PKS 0422+004 = OF 038 (Bolton et al. 1968, Austral. J. Phys. 21,
81; Fitch et al. 1969, Astron. J. 74, 612) is probably a BL Lac
object. On Jan. 3 it was observed to have brightened to V = 14.96
(from about 16-17); color indices were B-V = +0.53, U-B = -0.51.
