Optical photometry of parsamian 21.

SEMKOV E.H. and PENEVA S.P.

Abstract (from CDS):

Result. from BVRI photometric observations of the FUor-like object Parsamian 21 are presented. Calibrated BVRcIc magnitudes of the comparison star sequence around Parsamian 21 are given. Comparing our CCD photometric observations of Parsamian 21 in the period 2003 - 2009 with the data from Palomar plates showed no significant change in the brightness of the star for a very long period (57 years). Our conclusion is that Parsamian 21 is probably a member of the group of long-lived FUors and that the time-scale of the FUor phenomenon in some cases is much longer than that predicted in previous studies.
