Kazuhiro Nakajima revealed that MisV1061 is an Algol-type eclipsing variable with V-band variations of 12.14 mag at maximum, 12.81 mag at primary minimum, 12.55 mag at secondary minimum, and period of 3.0421 days.

MisV1061, R.A. 21h00m17s.97, Decl. +27o52'56".1 (J2000.0), is a new variable star discovered in the course of the MISAO Project from Nobuo Ohkura's unfiltered CCD images on June 19, 2000, comparing with Ken-ichi Kadota's unfiltered CCD images on July 24, 1999.

Nakajima observed it on 8 nights between July 21 and Aug. 19 in 2003 with 0.25-m f/5 Schmidt-Cassegrain and CV-04 CCD with V filter, and caught four minima.

Secondary2452845.22200.0008
Primary2452861.95840.0010
Primary2452871.07920.0006

The period is derived as 3.0421 days from these minima.

Here is the light curve of MisV1061 from total 730 observations. Comparison star is TYC2-2180.0228.1, R.A. 21h00m13s.9, Decl. +27o51'47" (2000.0), 11.65 mag(V). The phases on the figure were calculated by the ephemeris:

Primary minimum HJD = 2452871.0792 + 3d.0421 x E
