UGC 3697 (GB 1, the Integral Sign Galaxy and others) is an edge-on spiral with warped arms located approximately 151 million light-years away in Camelopardalis. Scientists believe the warping is the result of interaction with a dwarf galaxy.

UGC 3714 is the round spiral below and to the left (east) of UGC 3697. It is located approximately 140 million light-years away.
