V523 Aur = MisV0002 is a W UMa-type eclipsing variable     March 28, 2003 Nakajima, K.; Yoshida, S.; Kadota, K. Kazuhiro Nakajima revealed that V523 Aur = MisV0002 is a W UMa-type eclipsing variable with unfiltered CCD brightness variations between 13.7 - 14.7 mag, and period of 0.3303555 days. V523 Aur, R.A. 07h24m03s.56, Decl. +41o26'02".0 (J2000.0), is a new variable star discovered in the course of the MISAO Project from Ken-ichi Kadota's unfiltered CCD images in 1998 December. V523 Aur on Kadota's images Nakajima observed it on Mar. 18, 19, 20 and 26 in 2003 with 0.25-m Schmidt-Cassegrain and CV-04 CCD. Here is the light curve of V523 Aur from total 654 observations. Comparison star is TYC2-2965.0148.1, R.A. 07h23m19s.5, Decl. +41o22'22" (2000.0), 11.43 mag(V). The figure suggests that it is a W UMa-type eclipsing variable with unfiltered CCD brightness variations between 13.7 - 14.7 mag Here is the list of five minima observed on the four days. The period is derived as 0.3303555 days from these five minima.
