* Discovery Information

Seiichi Yoshida, MISAO Project; and Ken-ichi Kadota, Ageo, Saitama, Japan, discovered a new variable star MisV0898.

It was detected by the PIXY system as one of the candidates of new variable stars from images taken by Kadota, then confirmed by Yoshida.

* Special Notes

Identified with 2MASS 1800214-304831, (J=10.764 mag, J-Ks=0.739 mag. It is probably not a red variable because of the small J-Ks value. Seiichi Yoshida revealed that it is clearly found on the DSS 2 R-band and Bj-band images, which also implies that it is not a red variable.

However, Yoshida and John Greaves found that it is not recorded in any of GSC 1.1, USNO-A2.0, IRAS, 2MASS, UCAC1, GSC 2.2, despite of the bright peak magntiude (11.6 mag).

However, further research revealed that it is recorded in USNO-A2.0 and USNO-B1.0. The R.A. and Decl. was inaccurate.
