Nakajima, K.; Yoshida, S.; Kadota, K.

Kazuhiro Nakajima revealed that MisV0665 is an Algol-type eclipsing variable with unfiltered CCD variations of 13.18 mag at maximum, 13.84 mag at primary minimum, 13.26 mag at secondary minimum, and period of 1.6351 days.

MisV0665, R.A. 18h43m23s.82, Decl. -21o20'37".7 (J2000.0), is a new variable star discovered in the course of the MISAO Project from Ken-ichi Kadota's unfiltered CCD images taken on July 15 and Sept. 23 in 1999.

Nakajima observed it on 17 nights between Aug. 23 and Oct. 26 in 2003 with 0.25-m f/5 Schmidt-Cassegrain and CV-04 CCD, and caught four minima.

The period is derived as 1.6351 days from these minima.

Here is the light curve of MisV0665 from total 828 observations. Comparison star is TYC2-6292.0086.1, R.A. 18h43m38.4s, Decl. -21o22'50" (2000.0), 11.49 mag(V). The phases on the figure were calculated by the ephemeris:

Primary minimum HJD = 2452929.9033 + 1d.6351 x E
