Regarding T CrB, the star behaves in the same manner as in recent months. So we have no real clue when its outburst will happen.
These are my most recent photometric observations of this recurrent nova star (Fig. 1).
I am complementing my observations with a comparison of the spectra with data from AAVSO’s observer PROI (Fig. 2).
The blue spectrum corresponds to when T CrB was close to its peak brightness at the end of March. The red spectrum was captured three days ago, when this star seemed less bright.
