Times of minima of a W UMa-type eclipsing variable MisV1097October 11, 2003
Nakajima, K.; Yoshida, S.; Ohkura, N.
Kazuhiro Nakajima observed a W UMa-type eclipsing variable MisV1097, and revealed the unfiltered CCD variations between 13.04 and 13.74 mag, and period of 0.4688 days.
MisV1097, R.A. 01h15m28s.73, Decl. +41o19'59".3 (J2000.0), is a new variable star discovered in the course of the MISAO Project from Nobuo Ohkura's unfiltered CCD images between 2000 September and December, and revealed as an EW/KE type eclipsing variable by Ondrej Pejcha.
Nakajima observed it on 5 nights between Aug. 28 and Oct. 1 in 2003 with 0.25-m f/5 Schmidt-Cassegrain and CV-04 CCD, and caught four minima.
The period is derived as 0.4688 days from these minima.
Here is the light curve of MisV1097 from total 517 observations. Comparison star is TYC2-2808.0899.1, R.A. 01h15m17s.1, Decl. +41o25'00" (2000.0), 11.89 mag(V). The phases on the figure were calculated by the ephemeris:
MisV1097 is a blue W UMa-type eclipsing variable
