    Object of the Week October 7, 2012 The TAFFY II Galaxies UGC 816,UGC 813

    UGC 816

    UGC 813

    Taffy II galaxies AKA VV 769

    Andromeda

    RA
    01 16 20

    DEC
    +46 44 60

    MAG 14.2 P and 14.8 P

    TYPE S in interaction

    Last week while I was doing research on the Taffy galaxies (UGC 12914/5) I came across the 2002 AJ paper A Second Taffy pair by JJ Condon. This caught my eye and after seeing many referrals to this paper about the Taffies UGC 12914/5 I read it. I must say I was blown away by how much the Taffy II are morphologically like the Taffy I galaxies. They both have a strong molecular bridge the is caused by a long time of interaction between the two.

    I can't wait to try this pair this dark period! I wonder how much of the bridge between the two will be able to be seen? I look forward to hearing your observations of this odd pair that Arp did not put in his catalog of peculiar galaxies.

    The other bright galaxy is CGCG 515-11 MAG 15.1 but is not part of the interaction. If you would look at the NRAO image above and the DSS image below 2.6' West North West of UGC 816 is a faint dwarf galaxy that is interacting with the two larger galaxies and is part of the system. From the SDSS photometry this little dwarf is approximately 17.1 V mag and should be able to be seen by many of the telescopes in this forum under a dark sky. If you are able to observe this little dwarf I am sure you will be in the company of very few visual observers,

    At the time I write this I know of no visual observations of this Little dwarf that is part of the TAFFY II interaction so be sure the next time you are under a clear dark sky to,

    GOOD LUCK AND GREAT VIEWING!
