    Object of The Week, May,7 2017- NGC 5122 (Swift's Polar-Ring)

    Hello:

    [I am posting this on behalf of Jimi Lowrey, who is currently traveling. The OOTW is entirely his, and I have only done the formatting.]

    NGC 5122

    Virgo
    RA: 13 24 14
    DEC: -10 39 15

    Type S0 Liner

    MAG 13.8




    NGC 5122 is one of the best examples of the rare type polar-ring galaxy. It was found by comet hunter Lewis Swift on April 24, 1887 with his 16" Clark refactor. He recorded it "vF;vS;R; In finder field with Alpha Virginis"

    There is some thought that NGC 5122 might be or have been interacting with the disturb spiral MCG-2-34-45 which is 11.6' North East of 5122. The polar-ring points toward MCG-2-34-45.

    Recently Steve Gottlieb and I had a memorable view of this unusual galaxy. The core was really bright and looked like an edge on. The faint polar-ring were seen as a short extension with AV. I was surprised that the polar-ring was as easy to see as it was.

    So if you want to see a rare type polar-ring galaxy be sure to check out NGC 5122 and...

    "Give it a go and let us know!
    Good luck and great viewing!"

    Hi Akarsh,

    nice object...

    "Recently Steve Gottlieb and I had a memorable view of this unusual galaxy. The core was really bright and looked like an edge on. The faint polar-ring were seen as a short extension with AV. I was surprised that the polar-ring was as easy to see as it was."

    ... with which instrument and under which sky conditions?

    However i´ll give it a try...

    Dear Norman,

    This is Jimi's OOTW that I posted on his behalf. So I'm assuming that the instrument was Jimi's 48" telescope, and the conditions were as is typical of skies in Fort Davis. I joined Jimi and Steve for a couple days, but this observation was done before I was there, so I don't know how the skies were.
