The new object is located at R.A. = 11:43:55.93, Decl. = +10:46:55.2 (equinox 2000.0), which is 23" east and 10" south of the center of NGC 3839. Nothing is visible at this position on the Digitized Sky Survey or on his image of NGC 3839 taken on 2002 Jan. 19 (limiting mag 19.0). Itagaki has posted the discovery image at website URL http://www.k-itagaki.jp/images/psn3839.jpg. Nakano adds that six co-added 120-s confirming unfiltered CCD images (limiting mag 18.6), obtained by T. Yusa (Osaki, Miyagi-ken, Japan; remotely using a 0.25-m f/3.4 reflector near Mayhill, NM, U.S.A.) on Dec. 13.39, yield mag 16.7 and position end figures 55s.93, 55".2.
