Hello,
you may remeber that V442 And went into outburst in august last year. Well... it did it again! I have been following it since june (33 spectra!) without significant changes - but still some small variation to study later in more details. My spectrum from august 11th was in absorption, then on august 14th a significant emission appeared in Halpha spectrum. Since then, it is showing drastic V/R variations.
I posted all my 2018 spectra on my blog as a single graph:

Of course, it would be worthwhile to monitor the outburst as we do see daily (and even within the hour) changes in Halpha spectrum at the moment. R>5000 spectrographs is best to observe with.
Cordialement,
Olivier
