Type: galaxies (interacting)
Mag: B=12, V=?
Size: 1.412′ x 1.174′
Discovered in 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "pB, mE in the meridian, 2' long."
! F, 1.3'x1', E 160deg, very compact spiral with pB alm.stell.N. 0.5' s.f. which is a star apparently surr. by a dark hole some 25'' diameter.
F, 1.5'x1', lE 160deg, spiral with a pF almost stellar nucleus, 30'' s.f. is a bright star surrounded by a dark hole; see HOB22.
Listed as No. 127 in Arp's "Atlas of Peculiar Galaxies" (Astrophysical Journal Supplement, vol. 14, 1966.) He remarks "sharp absorption lanes over north side of perturbing galaxy."
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.0 mag galaxy. Their coded description reads IRRR,DIFHALO ELTO FO ATT TO SLEL STEL OBJ S.
Steve Coe, using a 13" f/5.6, notes: "Very faint, Small, round, not brighter in middle. This object is pB for pretty bright in NGC desciption. That may be so in Lord Rosse's 72", but in the 13" it is not much."
Observing site: Little Bennett Regional Park
[0h 39m 0s, -9° 0' 0"] The verriest smudge. Invisible in the 30mm, only glimpsed in the 12.5. The companion IC galaxy was invisible.
