Observing Notes

Harold Corwin

IC 4534 is UGC 9713. Javelle misidentified his comparison star. It is actually the star at 15 03 17.6, +23 55 10 (1950). Once this change is made, his measured position falls within half an arcsec of the nucleus of the galaxy. And his description (summarized by Dreyer) "pB, S, Ens, N" fits as
well.

However, in spite of the similarity of errors, Javelle did not use the same comparison star for IC 4532 (which see). He discovered IC 4534 three nights later on 28 July 1903, and the positions are about half a degree different.
