SUPERNOVA 1962R IN UGC 1810 This designation is being given to the presumed supernova 28′′ north-

east of the nucleus and in a spiral arm of the galaxy UGC 1810 (α = 2^{h}18^{m}.4, δ = +39^{o}09′, equinox 1950.0), recorded at m_{pg} = 15.9 on plates taken with the Lick Observatory’s 0.5-m astrograph during one week in Dec. 1962 and discussed by Kinman et al. (1982, A.J. 87, 314), who designated the object RR V-4.
