That's great news
Two comets in one year visible to the naked eye. And while we are waiting a year for Comet Ison to arrive here at earth we should get some pics from Curiosity as it passes near Mars. You can bet a lot of space orbiting instruments will be focused on Ison also. I wonder if Cassini will get a opportunity.
Comet 2011 L4 Panstarrs will be shining bright in early March around .5 mag.
Just can't get this image I generated to work here. Works when I copy/paste into a new tab.
Sure hope Ison stays together as it gets close to the Sun. Amazing this comet is coming from so far away and has taken millions of years to come by our way.
