Arp 279 and Arp 263 AAS 195th Meeting, January 2000 Session 72. The observations reveal that the gas in each system is extended as far as ten galactic radii in Arp 263 and three galactic radii in Arp 279.
Extended tails are present in both systems indicating the presence of tidal disturbances.
No tidally formed dwarf galaxies are found in these interactions. Arp 279 appears to be encountering an early stage interaction with a neighboring galaxy, Arp 279A. Arp 263, however, reveals signs of both early and late stage interactions. Higher resolution observations are needed to further investigate the properties of these interacting galaxies and do further kinematic analysis.
