Six new RR Lyrae stars with Blazhko effect

by Ivan Adamin in July-August 2013 (#1)

As part of VS-COMPAS data-mining program, here are six new pulsating RR Lyrae variables with the presence of the Blazhko effect listed. The research result on these objects is submitted to the VSX catalog for the first time by the VS-COMPAS team members. Photometric data from publicly available surveys (NSVS, CRTS, ASAS) was used a a source for light curves.

Below each object is presented along with the resulting folded light curve and some notes, if any.
