Kazuhiro Nakajima revealed that MisV1105 is a beta Lyr-type eclipsing variable with unfiltered CCD variations of 13.79 mag at maximum, 15.03 mag at primary minimum, 14.20 mag at secondary minimum, and period of 0.6331 days.

MisV1105, R.A. 20h14m38s.61, Decl. +41o56'14".3 (J2000.0), is a new variable star discovered in the course of the MISAO Project from Nobuo Ohkura's unfiltered CCD images on Sept. 26, 2000, comparing with Ken-ichi Kadota's unfiltered CCD images on Nov. 21, 1999.

Nakajima observed it on 8 nights between Aug. 2 and 22 in 2003 with 0.25-m f/5 Schmidt-Cassegrain and CV-04 CCD, and caught three minima.

The period is derived as 0.6331 days from these minima.

Here is the light curve of MisV1105 from total 779 observations. Comparison star is TYC2-3159.1206.1, R.A. 20h14m20s.7, Decl. +41o58'03" (2000.0), 10.65 mag(V). The phases on the figure were calculated by the ephemeris:

Primary minimum HJD = 2452873.9913 + 0d.6331 x E
