Observing Notes

Harold Corwin

While there is nothing at Frost's position, there are two obvious candidates for this number. Unfortunately, neither galaxy is the outstanding choice. One, a large low-surface-brightness dwarf spiral five seconds west and an arcmin north, matches Adelaide Ames's diameter and magnitudes in her 1930 Virgo Cluster catalogue (she worked from the same plates that Frost used 30 years earlier). But was this really the galaxy that she and Frost measured? Five seconds east at the nominal declination is a much smaller galaxy -- but it has a much higher surface brightness so might be picked up more easily in spite of its size.

In the end, I slightly favor the larger galaxy, but we'll have to take a look at the Harvard plate to be sure.
