Observing Notes

Harold Corwin

IC 3050 = NGC 4189, IC 3051 = NGC 4193, and IC 3064 = NGC 4206 all appeared in Schwassmann's list of nebulae in the Virgo Cluster. Their positions are all very close to the NGC positions, so I'm pretty sure that neither Schwassmann nor Dreyer checked the earlier catalogue closely before listing these as new nebulae.

There is no doubt about the identities; the positions and descriptions are too close to question. Adelaide Ames was the first to suggest all three identifications in her 1930 Virgo Cluster catalogue.
