ASAS-3 Light Curve

* Discovery Information

It was detected by the PIXY system as one of the candidates of new variable stars from images taken by Ken-ichi Kadota, Ageo City, Saitama, Japan, then confirmed by Seiichi Yoshida.

* Special Notes

Mati Morel pointed out the possible identification with Luyten's V915 Sgr. The range by Luyten (12.3-13.5p) is not too dissimilar to that of MisV0562 (11.8-13.8C). V915 Sgr is regarded as GSC 6870-00090 in Herbig's paper (PASP 70,605) and classified as RCB type with a period of 285.2 days, which can well refer to the period of MisV0562. If MisV0562 is V915 Sgr, it turns out to be a SR variable [vsnet-chat 2797].

However, the variability of V915 Sgr = GSC 6870-00090 was also detected in the MISAO Project. So MisV0562 is a new variable star [vsnet-chat 2803].
