don´t forget to observe the next periastron passage on February 1th 2021!!
This time there are very good opportunities to observe totally the rise and the descent of the parameters EW, V/R, RV and CA.
While I do not yet have spectroscopy capability, I've begun observing 28 TAU in B, V and I. My 1st upload was today, I expect a couple sets per week through February, but can continue longer. I am using the BSM network for images.
