Observing Notes

Harold Corwin

IC 4940 is also likely to be a plate defect. Seen by Stewart on the same Bruce plate as IC 4922 (which see), his description reads "F, S, E at 100deg". There is nothing like that within 10 arcmin of his position.

While working on SGC, I noted in my copy of IC2 that this might be four stars. However, the only four stars that I see on DSS that might have caught my eye twenty years ago are 3.5 arcmin south of the nominal position, and nearly form a square. So, they do not match Stewart's position angle, and are certainly not his object.
