LD 323 is one of the Lennart Dahlmark variables that so far has not made it into the GCVS namelists; and lacking an official name we will have to keep calling it LD 323 for some time. I have observed it on and off for about a year. There is also a series of observations by Steve Girard in late 2013.
The star varies quite regularly:
I have used VSTAR to analyse Girard’s and my observations. The Fourier transform method (DC DFT) in VSTAR gives a period of 88.9 days (using only the V data), which is for all practical purposes identical to the result, 88 days, that Sebastian Otero got in his analysis of NSVS data for this star.
