Corwin's Notes
=====
NGC 5142 has a star superposed just 3.4 arcseconds south of the nucleus. It
is clearly seen only in the SDSS image, but there is just barely a suggestion
of it in the combined 2MASS color image in NED. Unlike IC 3993 (which see),
this star is not particularly blue, so is probably not a supernova. It
certainly does not appear in the IAU supernova list.
Steve's Notes
=====
NGC 5142
18" (6/4/05): moderately bright, small, slightly elongated N-S, 0.5'x0.4'. Sharply concentrated with a very small bright core and stellar nucleus. Forms a similar pair with NGC 5142 2.3' SW with NGC 5143 2.3' N.
18" (7/22/03): fairly faint, small but fairly high surface brightness with a bright stellar nucleus and a slightly elongated faint halo N-S, 0.5'x0.4'. Forms a fairly similar pair with NGC 5141 2.3' SW and difficult NGC 5143 is just 2.3' N.
17.5": faint, small, small bright core, stellar nucleus, elongated ~N-S. Forms a pair with NGC 5141 2.3' SW. NGC 5143 2.3' N was not seen.
