Dear colleagues,

I checked the stars in the MISAO database. Here is the result. Unfortunately,
no evident variable star was discovered.
In general, I checked variability of all stars detected from the images. So
if some 2MASS stars behave variable, they can be picked up by the PIXY
System and some scripts as new variable stars, then announced as MisV
stars.
Best regards,
