Corwin's Notes

===== NGC 5860 = Markarian 0480 is a double interacting system. JH presumeably saw only the brighter, southern component as his accordant descriptions (from successive sweeps in early May 1828) read, "F, R, gbM, 20[arcsec]" and "Not vF, S, R, psbM, 15[arcsec]." Markarian's finding chart marks both objects. In my earlier position lists, I had two entries for the object, the second as "N5860A". A closer look at this showed that only one of the "N5860A" positions was actually for the companion -- my apologies for the confusion. This time around, I've labeled the components with directional designations.

Steve's Notes

===== NGC 5860 24" (7/1/16): at 500x; NGC 5860 is a merged pair of compact ellipticals in a common halo with the nuclei separated by only 9"! Overall the glow is fairly faint, fairly small, round and punctuated by a small bright nucleus (the southern component). The northern nucleus (listed in NED as NGC 5860 NED02) is fainter and quasi-stellar, perhaps 3"-4" diameter, and cleanly separated at 500x. A wide pair of mag 13.3/13.4 stars is 3' WNW and a third mag 13 star is 2' SW. 17.5" (7/15/93): faint, small, round, 30" diameter, small bright core. A mag 14 star is 1.1' NNE. Follows an arc of three mag 13 stars aligned NW-SE; the closest star of the three is 2.2' SW.
