I noticed new variable star near nova Sgr 2011 when I compared images of nova Sgr 2011 and V4744 Sgr (nova Sgr 2002 no.4).
It seems to be Mira or semi-regular variable as it has red color and showed slow brightness-change in 2002-2003.
There are no known variable star according to AAVSO chart plotter.
