V = 11.1;  Size 5.5x3.0;  SB = 14.0;  PA = 13d

17.5": fairly bright, large, small bright core, mottled oval disc ~N-S.  There 
is possibly a sharper light cut-off along the western side.  Third and brightest 
of three with N5982 7.5' WNW and N5981 13.8' WNW.

13": moderately bright, moderately large, diffuse halo N-S.  Brightest of trio.

17.5": fairly bright, fairly small, bright round core, stellar nucleus, fainter 
halo elongated 3:2 ~E-W.  Second of a striking trio with N5981 6.4' WNW and 
N5985 7.5' ESE.

13": fairly bright, small, small bright nucleus, slightly elongated E-W.  In a 
trio with N5981 and N5985.

V = 14.8;  Size 0.9x0.4;  SB = 13.5;  PA = 130d

17.5": extremely faint, very small, roundish (elongated NW-SE on POSS).  On a 
line with two mag 10/12 stars to the NW by 5' and 7'.  Located 8.2' W of N5981
