Summary description: eF, vS, R, bM (? PD 15')
NGC 2984 = IC 556, which see.
17.5" (4/1/00): faint, small, round, 25" diameter, weak concentration. The halo, which fades at the edges, increases to ~0.6' with averted vision. A mag 14.5 star is close SSW (33" from center) and a slightly brighter star lies 0.9' NE.
NGC 2984 forms a pair with IC 557 7' SE. The companion appeared faint, very small, elongated 2:1 SW-NE, 30"x15", weak concentration, very faint stellar nucleus at moments. The elongation was not always evident, so often I was just viewing the slightly brighter core.
