What's new here?

You may have already heard some buzz about Comet ISON, which has a very good chance of being a very bright and visible comet later this year (2013). But there is a decent chance that we have a preview naked-eye comet this month by the name of Comet PanSTARRS

PanSTARRS

PanSTARRS will make its closest approach to Earth (about 93 million miles) tomorrow – but it really will not be visible despite being at its closest state. Only a couple days later will it creep up over the Western horizon after sunset. On or about March 10th will it start to develop its ‘tail’. In the middle of the Month, the Comet should truly be visible. At time the Moon might interfere. PanSTARRS should be visible in the Western skyline for much of the rest of March.

The brightness of PanSTARR is estimated to be about as bright as a star in the Big Dipper. So if you can see the Big Dipper in your night sky, PanSTARR should be visible – albeit more streaky as a comet is want to be.

All of this comet discussion comes with a caveat – COMETS ARE VERY HARD TO PREDICT. A wise astronomer once said ” Comets are like cats – they have tails and do exactly as they please”. Many a comet has done something unexpected resulting in disspointing viewing: breaking up, not have the right tail orientation, etc. On the other hand, it could be even brighter than expected (-1 magnitude, not quite as bright as Sirius).

But hey, if you are out on a clear March night, it won’t hurt to glance Westward.
