A pulsating long period variable star with a long period of around 670 days. It varies in magnitude from 8.5 to 11.0 over its long period, with a smaller magnitude pulsation period of around a third of a day. There are no reliable distance measurements other that its far enough away that parallax measurements are currently unreliable.  It is the reddish brighter star located near the center.
