arp 249 is in the class appearance of fission. the atlas note says
"straight connection from faint material on e to middle galaxy". my image
shows that easily, and also the jet or plume pointing sw from the s galaxy.
these are both easily seen in the atlas image, but my image (especially
the 2x detail) also shows a jet of material exiting the southern
nucleus perpendicular to the line of connection that cannot be seen in
the atlas image. it is, however, easily visible in 48-inch palomar schmidt images taken in
1959 and 1994. i suspect it was just the choice of processing that left it
out of the 200-inch atlas image.
the entire group (two or three galaxies,
depending on the cataloger) is cataloged as ugc 12891. there was some
rotation between my 2005 and 2007 images. i did not crop off all of the
misaligned edges because i wanted to leave the kug 2357+228 galaxy in the field,
right at the n edge. the misalignment shows up more in the negative image.
