Observing Notes

Harold Corwin

IC 3056 is most likely DDO 114 = UGC 7249 with a one-degree error in its declination. There is nothing at Frost's position that he could have picked up on his plate (the galaxy that Glen Deen suggests is much too faint and small to have been seen on the early Bruce plate).

The identification was first suggested by Adelaide Ames in her 1930 monograph and catalogue of Virgo Cluster galaxies. Though the position angle is a bit off Frost's (he says 50 degrees, Ames has 60 degrees, and I measure 67 for the main body of the galaxy), the position is indeed exactly one degree south of Frost's nominal place. His brief description is appropriate, too: "Streak, E 1 arcmin at 50 degrees."

The accurate position is a bit difficult to obtain as there is no obvious structure to the galaxy aside from the patchy streak. The position I've adopted from GSC2.3 more or less represents the entire galaxy, and certainly allows for unambiguous identification of this low-surface-brightness dwarf in the Virgo Cluster.
