Notes: I could not see Arp 46 with DV. I saw it on-and-off using AV. I had the impression of a teardrop shape aligned NE-SW and with the SW half brighter than the NW half. Also in the field to the NW is UGC 12667. It is not part of the Arp. This galaxy is 1.5 x 1.2 arcmin and magnitude 13.5. It was easily visible with DV throughout. It appeared as an oval in ratio 4:5 with the long axis aligned roughly NS, with the bright core offset a little towards the N end. There were very vague suggestions of structure. |
