Discovery Information
Kazuhiro Nakajima, Mie, Japan, discovered a new variable star MisV1339.
It was picked up during time series photometry of MisV1317 in the course of the MISAO Project.
The light curve suggests it is a semi regular variable with an unfiltered CCD amplitude of 0.25 mag between 10.02 - 10.27 mag.
Not only the long term variation, a short term oscillation with an amplitude of 0.10 mag was also confirmed by the time series photometry on three nights.
MisV1339 is almost constant at 10.323 +/- 0.022 mag in the NSVS data.
Special Notes

MisV1339 is almost constant at 10.323 +/- 0.022 mag in the NSVS data.
Michael Richmond researched the TASS Mark IV database and found one feature in the I-band, but otherwise no obvious variations was found (light curve). The mean color is (V-I) = 0.79.
Mitsugu Fujii's spectrum on 2008 Mar. 5 (the red is MisV1339) is a normal spectrum of a G-type star.
