Scientific paper

Data obtained in February and March 1984 with a UBV photometer attached to the 91-cm McDonald Observatory reflector, and with a V color photometer attached to the 35-cm Yunnan Observatory reflector, of 17 of the 24 variables in Coma reported by Archer (1959) are presented. Observations made for more than half of the periods given by Archer show no variations larger than 0.07 mag in V magnitude for these stars, and it is suggested that Nos. 3, 4, 7, 14, 16, 17, 18, 19, 21, 22, and 23 are not variables. Small variations seem to be present in Nos. 4, 14, and 17, though it cannot be determined if these stars are small-amplitude variables of some other type.
