Observing Notes
Harold Corwin
IC 3556 is one of the galaxies in the NGC 4556 group. So, even though Wolf's photographic position in his 4th Konigstuhl Nebel-List is exact, CGCG, MCG, UGC, and PGC have all ignored the number in favor of NGC 4563, NGC 4558, NGC "4536" (typo for 4563), and NGC 4558 (again), respectively. Wolf identified the NGC galaxies correctly, too, giving good positions for them, so we can be certain that IC 3556 is a "nova." See NGC 4558 and NGC 4563 for further discussion.
