Where and at what time do I look to the sky? I have been looking day and and night and can't see anything
I am in Southern Illinois.
Silly question, but are these the only dates to view it?
Thank you in advance gang.
The comet will get super bright as it gets super heated from the super sun. Then one of two things will happen: The comet will either break apart from the heat, ending the show and disappointing billions, or it'll survive and have a brilliant glow that some suggest may be so bright, the comet will be visible not only at night, but during the day as well.
The comet is just barely visible to the naked eye -- a cosmic smudge, but it's there. The trick is, each day that passes closer to Thanksgiving, the comet is getting closer and closer to the sun, making it more difficult to see in darkness as it's rising and setting closer to the sun.
But at least for Wednesday and Thursday nights, you have a chance. Trick is to get up about 90 minutes before sunrise (about 7:20 a.m. in Seattle) and look very low in the eastern sky (near where the sun would rise). If you can use a star chart, like Skyviewcafe.com (or smartphone app!) to find Spica, ISON is close by.
Here is a chart for Seattle for Thursday morning at 5:40 a.m., courtesy of SkyViewCafe.com:
We are, as I said, in a race between seeing ISON when it's still dark as this program indicates the comet rises at 5:27 a.m. on the flat horizon but early morning twilight begins around 5:45-5:50 a.m. Seattle also has a challenge in that there are A) city lights and B) mountains to our east. Best plan is to get somewhere dark with a good view to the east/southeast, or cross your fingers that the comet survives Thanksgiving and we get some more clear weather in December and early January.
*If* ISON survives its Thanksgiving encounter with the sun, then it should become brilliantly bright with a long tail as it shows off its heat glow. It'll take while for it to get far enough away from the sun to see at nighttime but by the time we get into mid-late December, ISON should be above the horizon for much -- if not all -- of the nighttime hours. ISON makes its closest pass to Earth on its return trip out on Dec. 26 and sure enough, SkyViewCafe says the comet will be visible all of Christmas Eve Night and Christmas Night.

Hey NGC & Maria - Have you seen this thread regarding missing data from a number of the cameras tasked with solar watching? Data Missing From SECCHI-A COR2
Do either of you have any thoughts? Seems odd, but for all I know they shut down multiple cameras all the time in the event of large flares and/or CME's. And what was captured right before the shutdowns looked pretty big...

????????????........for your image link.
No directory found! Please check that the input date is in YYYYMMDD format.
There is nominally a two day delay from present for download and processing before images are available for the movie tool.
See the SECCHI Image Gallery link for available dates
