Sc(s)II CD-1698-S Jan 4/5, 1981 103aO + GG385 45 min NGC 3055 has weak features of a barred spiral. Two high-surface-brightness inner arms start from the ends of the bar and, by branching, give rise to the luminous, massive arm fragments that cover the outer disk. The redshift is v_o = 1747 km/s. SAB(s)c (de Vaucouleurs) Very small, very bright nucleus in a short narrow bar. 2 main knotty arms with much branching, one stronger and longer. Heidelberg Veroff. Vol. 9, 1926 dimensions (1.2 arcmin x 0.6 arcmin) for bright part only. Spectrum: Lick Obs. Bull. 497, 1939. HMS Note No. 076 Weak exposure that shows H{beta}, H{gamma}, and {lambda} 3727 as emission features. |
