Positions are based on nine GSC 1.2 reference stars with rms resudials 0.09" in R.A. and 0.12" in declination. The final position for RY Ser is 17h 23m 07.199s -12o 48' 09.43" This is a weighted mean from the three positions - one from each image (Vanmunster's have assigned weight 1 and Hendens weight 5).
