| Description | Definitely signs of interaction here, in addition to "companion". Arp's remarks, "Position of larger member. Arm appears wrapped around cylindrical comp." seems apt. We have a nearly face on galaxy, with a heavy arm connected directly to edge-on companion. 3rd, tiny, galaxy (also edge on) probably in the background. This observation started quite transparent, but ended up shut down due to clouds. |
