    Default Possible naked eye comets to watch.



    In another thread Peter made mention of there being a naked eye comet about.

    Turns out we might get lucky.
    There are three to keep a eye on.

    21P/Giacobini-Zinner.
    It's supposed to be brightening July through August and might reach 6th magnitude putting it at the threshold for the naked eye.

    38P/Stephan-Oterma.
    Perihelion is on the 26th August 2018 making it easily accessible to backyard telescopes. It remains well placed for 2018 and according to NASA the point at which the comet is closest to Earth will be in Jan 2019 as Earth catches up with the comet in it's orbit, how bright the comet will be will depend on it's perihelion passage and how well it has reacted to that.

    46P Wirtanen
    Perihelion occurs in the 12th December 2018 and should reach magnitude 3, making it easily naked eye!


    For the record I have observed 46P Wirtanen already and looking forward to watching it grow brighter.
    At best I would hope these all become easy binocular or naked eye targets.
    So add them to your observing lists and let's hope for the best and clear skies to enjoy it!

    Thank you Clinton for the alert!

    The 46P Wirtanen X-Mas comet, will it be also visible for us in north?, or just for you in the south.

    Clear skies,

    JG, I set Skysafari to the X-mas date and below is the screen shot, should give you guys a good idea of if you have a shot at it or not. Looks like it will be in Taurus at the time.

    Thank you Clinton,

    it will be very tough, we will need a big ladder to pull it out of the horizon haze, my guess.

    I have not used Stellarium for ages but I believe you need to do a minor body update? It's early in the morning and the brain is still fuzzy.

    I've added comets before to it but can't seem to find this one to add. I even double checked my method. Anyway, thanks to the screen shot you posted I know where to find it
