* Discovery Information

Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and Ken-ichi Kadota, Ageo, Saitama, Japan, discovered a new variable star MisV1024.

It was picked up by Yoshida from the candidates of new variable stars detected by the PIXY system from images taken by Ohkura comparing with images taken by Kadota. Kadota and Yoshida judged it as a real variable star.

Taichi Kato pointed out that this object is identified with a S-type star NSS 49.

The identification with the 2MASS data is by Taichi Kato.

* Special Notes

Because it is identified with IRAS 19596+3350 and an S-type star NSS 49, it is probably a red variable. But the 2MASS magnitude is J=7.312 mag, J-Ks=0.729 mag, so the J-Ks value is fairly small as a red variable.

Brian Skiff commented that the 2MASS J-Ks value may be erroneous, probably because of saturation or errors in the data-reduction.
