Comet ISON will move through perihelion today

from io9:
The so-called "Comet of the Century" is about to have its much anticipated brush with the Sun — the results of which could be visible to the naked eye. Thankfully, NASA is tracking ISON's journey in realtime, and here's how you can watch the drama unfold.
Scientists say Comet ISON is already starting to buckle under the pressure and it may not survive. The Sun's gravitational pressure and heat could cause the object to disintegrate before it has a chance to light up our skies.
NASA is tracking the comet's journey with the SDO (Solar Dynamics Observatory) spacecraft which will off-point at three different positions as Comet ISON moves through perihelion. The comet, which is traveling at more than a million kilometers an hour, is scheduled to reach its critical phase around the Sun between 12:45 pm and 1:00 pm ET (9:45 am and 10:00 am PT).

I tried to see it earlier this month, but no luck.

But I did get some great views of Mercury, which I don't see often. Hoping for better luck in early December.

The best time we had seeing it was going up on the tundra at 12000 feet, but it was visible right in town too, as you say. My mom called it "Ha-lay Bopp" because my sister-in-law's name is Hale, pronounced Ha-lay :-)
Other great comets I've seen were West, and Hyakutake, but the very best one was Ikeya-Seki in the winter of 1965-66. We went up in the foothills and saw the tail stretching over halfway across the sky.
I waited twenty years to see Halley's Comet, and I have to say it was a disappointment. But comets are unpredictable. I was expecting Ison to be visible in the evening in December, but apparently it's still going to be in the morning. It must be going around the sun in an orbit almost perpendicular to ours.

My dog & I walk around 4-5 am most days and I saw something low in the east that I wasn't used to seeing. Came home & looked it up to find out it was the comet. Very cool!

for the past week or two and have caught it a few times in a decent sized pair of binoculars. ( light pollution from the sun and a nearby city make them a requirement for seeing ISON) Sadly the sky has been overcast for the majority of the time so I will just have to wait for better conditions.
