Description

UGC 3697, 146 million light-years away (For H0 = 69.6),

features warped arms, which are thought to be the result of

interaction with the galaxy UGC 3714, located to the south-east.

"The central region is reddened mostly by age,

and partly by dust. Star formation is occurring

along the length of this remarkable 'integral sign' galaxy."

(JAMES D. WRAY - THE COLOR ATLAS OF GALAXIES (1988))
