Comet ISON Becoming Visible to the Naked Eye

As Comet ISON, also known as C/2012 S1, nears the Sun, it is rapidly brightening, with some reporting that they can see it (under very dark conditions) with their naked eye.  The magnitude as of November 14 was recorded as +5.4, and should be soon visible to the general public observer by the time it reaches +4.  Of course, the comet's increasing proximity to the Sun over the next few days will interfere with its visibility and counteract, to a degree, its increase in magnitude.  It is to be seen just before sunrise in the constellation Virgo, very near its brightest star Spica (to its west until November 18-19...then to the east).  I'll have one opportunity to view it tomorrow morning, if I'm awake and the clouds aren't obscuring my view.  Then for the rest of the week, I'll be inside a building at the time at work. 

It's still unclear how bright Comet ISON will get after it rounds the sun...or even whether it will survive the close encounter.  So it might be a good idea to get in your observations before the comet gets too close to the heat...
