AAVSO b Persei Results for November 2023 primary eclipse As we can see, the timing predictions of the eclipse main ingress and egress are reasonable, but the light curve of the prediction near the mid-eclipse needs some work. Most likely the sizes and brightnesses of the B and C stars. These data are significant in that we hope to gain a better approximation of the stellar sizes. The predicted eclipse date was determined by extrapolating the best fit dates of mid eclipse of past eclipses into 2023. The approximate sinusoidal curves are the fits to the out-of-eclipse data from 2018-19.
