Corwin's Notes

===== NGC 4702 = NGC 4692. D'Arrest has just one observation of NGC 4702 on 4 March 1867, calling it "Doubtless a very small, very much compressed cluster." There is nothing at all in his place. Exactly a minute of time preceding, though, is NGC 4692 which d'A has on two other nights, 16 March 1864 and 3 March 1867. Given the three or four nearby field stars around the galaxy, it is possible that d'A could have believed that he had found a small cluster. While the identity is not certain, I'm confident enough of it to have included it in the position table without colons or question marks. My thanks to Wolfgang who asked about this object.
