Many thanks for it. I have downloaded your image and examined it by
the PIXY system.

The PIXY system detected 1181 stars from the image. But V4334 Sgr and
MisV0001 were not detected. No other known variable stars are in this
field.

Actually, MisV0001 is found on the image. The PIXY system could detect
stars brighter than 17.35 mag even they are not recorded in USNO-A1.0.
But MisV0001 is fainter than 17.35 mag. My estimation by hand is 17.5
mag. 

I guess you have already reported to VSNET the magnitude (actually,
only the upper limit) of V4334 Sgr but you have not yet reported the
data of MisV0001. Would you please let me report the magnitude of
MisV0001 to VSNET and VSOLJ as observation by "Mis"? 

Maybe I can find another new variable star in this field in the
future. Then would you please let me report the magnitude data on your 
image, too?

The image information output by the PIXY system is as follows.
