V442 And (again, again, again!) in outburst

V442 And is again in ourburst. Here is a comparison between a spectrum taken the night of october 5th compared to the one taken a week before.

It is great as TESS (a satelite surveying the sky for exoplanets transits) will observe it starting next week.





Observatory in the morning after outburst discovery...



Spectrogram with BeSS spectra until oct 18th: 2.6 days period is visible as well as an increase of the emission (first spectrum substracted so only emission is shown here)
