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

The magnitude are measured automatically by the PIXY system. Image
observers' names are noted after "Mis", except for ones taken by
KenIchi Kadota.

V997 Sgr is 2.4 arcmin from MisV0844. No star brighter than 14.0 mag
was detected at the cataloged position of V997 Sgr. However, V997 Sgr
is a short period variable star between 13.8 - 14.6 mag. On the other
hand, MisV0844 is probably a red variable, considering the large
magnitude range and the identification with IRAS 17570-2947. Therefore, 
MisV0844 is probably another new variable star. MisV0093 is 3.1 arcmin 
from MisV0844, which is another variable star.
