S. P. Maran and R. D. Chapman, Goddard Space Flight Center, report that analysis of the 10-GHz measurements by Seaquist et al. (1979, A.J. 84, 1037) indicates an apparent variation with a period of ~ 6.39 days. This variation may correspond to the visible-light periodicity reported by Kemp et al. (IAUC 3421). If so, this result is consistent with the hypothesis that the high-frequency radio emission of SS 433 is thermal, although the low-frequency emission may be nonthermal.
