I don’t know of any reported variability of Sk -69 202. I’d be mildly surprised if it wasn’t variable.
A good number of LBVs are accessible to amateur observation. AE And and AF And are on my observing program. Eventually I’ll take a look at others in M31 and make start on those in M33. It’s a shame that the LMC and SMC never rise here.
Your mission, Robin, should you choose to accept it, is to take spectra of AE & AF And. This post will self-destruct in five seconds.
