Observing Notes
Harold Corwin
NGC 4139 = IC 2989. The RA's of this and its companion NGC 4140 are 5 minutes of time too large. When corrected by this amount, the positions agree closely with those for IC 2989 and NGC 4077, respectively. The descriptions clinch the identities, and RC3 is correct.
This pair was also seen by David Todd during his search for "the trans- Neptunian planet." It is his numbers (14a) and (14b), as well as (16a) and (16b). See NGC 3604 for more about David Todd and his search.
