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.
This object and V949 Sgr, a nova in 1914, are at the same position within 12 arcsec. Maybe it is a recurrent nova or the nova in 1914 was just a red variable.
Special Notes
Taichi Kato identified with V949 Sgr, a nova in 1914. MISAO's observations, followed by Patric Schmeer's observations, revealed that it is not a nova but a red variable (IBVS 4845).
