On the Presumed Pre Supernova Stage for Type II Super-Novaend a lower mass limit of about 10∼14 M. for stars undergoing the outburst is confirmed on the basis of the more recent evaluations. Finally, the possibility that the presupernova type II stage could be represented by the small amplitude irregular and semiregular red variables with large masses belonging to young population I is briefly indicated.

Synchronous Three Colour Stellar Photometry at the Catania Astrophysical Observatorys and the efficiency of this photometer are briefly described. At present the instrument is used for simultaneous UBV photometry of flare stars. A graph of simultaneous measurements in the UBV system of a flare of EV Lac is shown. A more detailed description of the instrument had been published else
