Wow, I think I just wet my pants. Visible in daylight!

 Normally it takes a while after discovery to calculate an accurate
 orbit, but this comet was found on pre-discovery sky surveys (where it
 was previously overlooked as a comet) and so they have 9 months of
 data (over 50 orbital datapoints). What makes it incredible is the
 nearness with which it is going to skim past the sun (.012 AU) and
 then the nearness with which is flies past the earth (.4 AU). This
 comet has the chance of being visible in a broad daylight sky,
 brighter than the moon. This will be an incredible object from Nov. to
 Jan. in 2013/2014. Currently, this comet is known by the following
 designation: C/2012 S1 (ISON)

 If you want to hang out with the comet nerds, including at least one
 of the discoverers of this comet:

 Before this, we were looking forward to another great comet in the
 Spring of 2013 (known by the designation C/2011 L4 PANSTARRS ) This
 comet alone would be enough to make most comet lovers wet their pants,
 as it is expected to flirt with negative visual magnitudes in March
 2013: http://www.aerith.net/comet/catalog/2011L4/2011L4.html but it
 has now been joined by a very big brother that looks to wildly
 overshadow it.

 2013 is going to be a once-in-a-lifetime year for comets.

Yes! Interesting to note that the most recent daylight comet was in 1910:
http://en.wikipedia.org/wiki/Great_January_comet_of_1910

If you notice the box with the orbital characteristics of that 1910
comet, you will see: Perihelion = 0.128975 AU
C/2012 S1 (ISON) has a calculated Perihelion of 0.012 (10 TIMES CLOSER
to the sun).

You just wet your pants and it's visible in daylight. 

That's more information than I really need, thank you very much.

;-)

So the Russians discovered this comet, eh? Sounds just like back in the cold 
war. No matter what we in the West ~really invented~ they claimed to have 
invented it first. From the television to the light bulb to being first to 
orbit the earth. Wait, they really were in space first.

Oh well. This comet really does sound amazing. Hope we'll be able to see it in 
New Toronto...

;-)

cheers,
frank
