Object name: ARP091
Designation(s): ARP091, NGC5953, NGC5954, NGC5951,
Arp 91/NGC 5953-4 is a well-studied pair of interacting galaxies in Serpens Caput about 100 million light-years distant. Arp put them in his category for Spiral galaxies with high surface brightness companions on arms. He made the comment: "Broad peculiar arm to companion, then absorption; faint extension from companion." This appears to refer to the odd band of stars coming from the south end of NGC 5954 (left) and going to NGC 5953 but suddenly appearing to be cut off. I have to wonder if NGC 5953 is slightly in the foreground and its dust suddenly blocks the light from this star stream. In the SDSS image, it may be faintly seen reappearing after passing behind the densest part of NGC 5953. The SDSS image with its three IR channels shows very reddened dust or maybe population 1 stars right where the stream appears to end. I didn't see this color in my image. Unfortunately, seeing was 3.5" when I took my image so it is pretty fuzzy and low resolution. It is on my reshoot list if the weather will ever cooperate. The last part of Arp's comment likely refers to the huge tidal cloud of stars about NGC 5953. I assume 5953 is the "companion" and the funny star stream the "arm" it is on.
