                   HR 7923 IS A VARIABLE STAR      

  The bright star HR 7923 (SAO 106396) was observed by the author with the
10 inch cassegrain reflector of the Nessa observatory. Photoelectric 
observations were carried out in V band on 29 nights between 27 October 1986 and
20 January 1988. The star SAO 106376 was used as the comparison star. The
observations are given in the table (the magnitude differences are in the
sense variable minus comparison).

  From these observations I found an amplitude of 0.2 mag. in V and a cycle
length of 100 days. The spectral type of HR 7923 is G8III and it is possible
that this star is a semiregular variable or an RS CVn variable. Further 
observations of HR 7923 are necessary to determine the type of variability more
exactly.
