While observing last night at a local observing site north of San Francisco with my 18" with, I took a look at Arp 7 (aka MCG -03-23-009 = VV 28 = PGC 24836) and was surprised to clearly see a relatively bright superimposed star, roughly mag 13.5 or perhaps brighter. I had with me Alvin Huey's observing guide for the Arps and he doesn't mention the star with his 22". Nor does Dave Tosteson with a 25" in Jeff Kanipe and Dennis Webb's observing guide to the Arps. At first I thought this might be a supernova, though when I got home this morning I checked the 2MASS image and it clearly shows a superimposed star on the east side of the core. I wonder if others have looked at this galaxy and noted the star? SQM-L readings ranged from 21.37-21.44 last night at this site (Lake Sonoma)
