Title of the communication: Light curve of W COM during 1994-1996
Preliminary abstract (12 lines max.): We report the preliminary results of CCD BVRI monitoring of W Com from March 1994 to June 1996. The observations were carried out at Perugia, Roma and Torino Astronomical Observatories. In this period the mean magnitude of the source was the higher observed in the last 20 years. Two major outbursts, showing complex structures and peaked in March 1995 and February 1996 respectively, are visible in the light curve. In the historical light curve of W Com the 1940, 1968, and 1995-1996 outbursts are spaced of about 28 years, supporting the idea of the existence, in this source, of a quasi-periodic fluctuation.
