V538 Cas has a diverse history. It was discovered to have variations of about 0.6 magnitude, but more recent observations showed very small variations.
In order to throw some further light on this object, I thought it would be interesting to make observations to see whether the star is a variable star after all. The star is around 7.6V and is therefore rather too bright for many telescopes and surveys, but the AAVSOnet Bright Star Monitor is a suitable instrument.
I submitted a proposal for time on the BSM for monitoring of V538 Cas and it got accepted. The first observations have been made. Preliminary analysis of a couple of weeks’ data show not much variability in this star. It will be interesting to see whether that holds over longer time spans.
