           NOTE ABOUT THE VARIABILITY OF HD 23 838



   In IBVS No. 2654 P. Vivekananda Rao et al. report on the probably very
slight or non-variability of HD 23838 = HR1176. While their conclusion
appears correct for the limited data available, it should be pointed out
that the comparison star used, HD 23728 = HR1170, is a known Delta Scuti
type variable, V 376 Per, 5.8 - 5.91V, periods 0.097 and 0.067 d. Thus the
small amplitude variations of about 0.05 V shown in Figure 1 (unless they
are indeed purely observational errors) may be a combination of the variability 
of both HD 23 728 and HD 23 838. Small wonder that Delta m (var-comp) and
Delta m (check-comp) show the same mean scatter of +-0.02. It would have 
been of interest to see a companion figure for Delta m (check-comp).
   Although no real variation of HD23 838 is apparent from these observations,
they are not sufficiently numerous to rule out an eclipsing type of 
variability, especially as no SB period is available for guidance.
