A series of spectra covering a period of variability could be interesting. (The clouds rolled less than a minute after I finally got the star on the slit of the ALPY600 when it finally cleared the rooftop at 16 deg altitude). Although extremely noisy, the spectrum is also consistent with the “normal star” description)
This appears to be a strange object – at first sight of the AAVSO light curve, it almost looks like a poorly sampled eclipsing variable with a period of about a day and a bit: but it makes little sense that it has suddenly started to vary having apparently been non-variable up to this point – and with at least half a magnitude of variation as well now! Odd!
