[vsnet-chat 6818] Is FASTT2 1892 an RS CVn variable ?



The star GSC 368-141 = FASTT2 1892 = 1RXS J162226.6+000721, is showing
a slow rise of nearly 0.2 mag for the last two years in ASAS3 data
(http://vsnet.astrouw.edu.pl/cgi-asas/asas_lc/162226+0007.4), in addition
to 0.1 mag scatter or possible short term variations.  TASS Mk III data
from 5 years ago
(http://stupendous.rit.edu/cgi-bin/tass_curve2.cgi?245.6099_+00.1230)
even has it another 0.1 mag fainter.  
Could this be due to a secular change in the starspot activity,
assuming this star is an RS CVn variable ? 
2MASS J-Ks and TASS V-Ic points to an early K type star.
