NGC 1569 is a galaxy which is probably situated close to the Local Group,
and has been considered as a member galaxy by
Arp (1986), together with its neighbor in the sky,
Today, however, most authors take them as neighboring non-members (e.g.,
van den Bergh 1994).
Kraan-Korteweg and Tammann (1979) suggest they might be
members of the Maffei 1 - IC 342 group. As both galaxies lie approximately in
the direction of the neighboring Maffei 1 and the M81 groups, their role in
the Local - Maffei 1 Group dynamics might be interesting.
Local Group candidate UGCA 92 is a close neighbor of
this galaxy, which may indicate a physical relationship of some kind.
The image in this page was obtained by the Hubble Space Telescope's WFPC2
camera, and processed by Mischa Schirmer; I grabbed it from the mailing list
astro at naa.net. It was composed from two blue, five green and two red as
well as 4 near-IR exposures.
