Probably it is a mira type star. But they say the amplitide of a mira
type star is larger than 2.5 mag, and if it is smaller than 2.5 mag,
it is a semeregular variable. I know the threshold is for V mag and I 
guess it should be smaller in case of unfiltered CCD images. But I do
not know the correct threshold. So in principle, the type is attached
based on the 2.5 mag threshold.

Best regards,
