Title of the communication: Quasar 3C 345: similarity in behavior of optical polarization during the flares connected with the ejection of superluminal jet components.
Preliminary abstract (12 lines max.): We present the results of optical polarimetric observation of quasar 3C 345 made during 1983-1993. The analysis of these data together with all observations published earlier revealed close similarity in behavior of optical polarization during two large s(slow)-flares occurred in 1982-1983 and 1991-1992. In particular there are some evidences for the systematic rotation of position angle with similar velocities (50 and 35 deg./100 days) since the beginning up to the end of the flares. In both cases its ending value (theta=90deg) coincides with the position angle of parsec scale radio jet. Earlier the comparison of VLBI data and total optical light curve suppose the connection between s-flares and the ejection of superluminal components of 3C 345 parsec scale radiojet.
