Corwin's Notes

===== NGC 4937 may be a compact asterism of 6 or 7 faint stars about 2 arcmin northwest of NGC 4940. Both were found by JH on 3 March 1837; he describes NGC 4937 as "eeF, S, R; the preceding of 2; a * 7m, just at northern edge of the field." NGC 4940 is "F, S, R, 15[arcsec]. The following of 2." While the identification of NGC 4940 is not in doubt, there is nothing but a single faint star at JH's position for NGC 4937. RNGC has this as "nonexistent", but notes a "close ** s"; this may be the two stars at 13 04 42.6, -47 13 44 (the two are not actually particularly "close" on DSS2 at eleven arcseconds separation). This leaves the asterism, just 20 arcseconds across, as the most likely candidate for JH's object. But I've flagged it with colons just in case he may have mistaken the star (with a question mark) for a small nebula during a moment of bad seeing.

Steve's Notes

===== NGC 4937 14" (4/2/16 - Coonabarabran, 160x): this knot of faint stars appeared as a very faint, very small glow (20"). Occasionally two extremely faint mag 15.2 and 15.7 stars "pop" within the glow. Located 2' NW of NGC 4940.
