Wink Comet C/2012 F6 (Lemmon)

Comet C/2012 F6 (Lemmon) will soon be reaching naked-eye visibility. However it is currently passing high over Antarctica and visible only to southern hemisphere observers. It will be nearest to Earth on 2013 FEB 05 and nearest to the Sun on MAR 24. Its estimated peak brilliance of +4.2 should occur on MAR 20 while it is too near to the Sun to be seen by naked eyes.

Perhaps the woos will deem this the comet of doom that can only be seen by conspiratorial astronomers at the South Pole.

After the comet passes perihelion, it should become visible to naked eyes in the northern hemisphere. Iíve created six related graphics with data that can be seen at: www.CurtRenz.com/comets

Photos and descriptions of the comet would be welcome additions to this thread.

Don't forget to make certain that the camera is out of focus first.

What I would like to know is for a given date where in the world would I be able to see the comet and how bright would it be and where in the sky will it be? Then if necessary I can have a holiday in a place where I can see it.

Well, there is likely to be a better one along late in the year.
Curt described it in an earlier thread.
http://www.internationalskeptics.com...d.php?t=244625

As for this one- bear in mind that it's not a (hugely) bright object. Naked eye visible, (just), but you would want decent binoculars, I'd think.
Curt's equatorial chart gives you a fair idea. Combine that with any free astronomical software like Starcalc or Stellarium and you can work out where to go.

Incidentally - re the joke about photographing a S. hemisphere object from up north, here's a link to one of the most incredible pictures ever- The sun, photographed through the Earth by neutrino "light".

It will be very difficult to do that as there is no knowing how bright a comet will be.
Comet McNaught was no expected to be a once in a lifetime show- but it was.

This is what we saw when we walked out on the beach in Hermanus South Africa.

Because there is no knowing how much gas will come off a comet it cannot be predicted long in advance - WHERE to see it can be.
