The Be stars HR 1960 and HR 2968 have been monitored from 1978 to 1998 in Geneva photometry and from November 1989 to March 1993 by the Hipparcos satellite. A spectroscopic survey of these stars started in September 1998. Both stars show luminosity variations with a period of 395 d and 371 d for HR 1960 and HR 2968 respectively.
