According to Starry Night Pro, as of now, the apparent magnitude is 10.7 I was wondering what your own estimate would be. Well done. Conn

I'm hoping to see it tonight, I wasn't able to go observing last night, looked like a nice sky.

I could not find a known comparison star in my image but Heavens Above gives a magnitude of 13.1 for that date. No significant tail observed.
The position for my image was RA 02h 03m 45.0s, Dec +63° 32' 57.5"

I am a beginner and I would like to see this comet but I am unsure how to find it .
If I put in the RA and DEC co ordinates you used last night into my goto would I see the comet with a 40 degree eyepiece at 2.00 am tonight.
Or are there more up to date co ordinates for tonight available.
I see the chart on comet chasing but do not know how to find the RA/DEC for tonight.
Thank you
Mark

One second Mark, I see you're from Drogheda so the coordinates will be different.

Pretty close after all, it is 54m miles away I suppose:)
Positions for all kinds of sky objects can be plotted on Stellarium

Thank you for the information. I believe I have found co ordinates from Drogheda at RA 01h38m23s and DEC +64°44'13" from this website.
in-the-sky.org/cometephem.php?obj=ck14e020
The website does not give a particular time to look it says visible all night, the comet chaser site mentions 1.50 am.
Do I point my scope at these new co ordinates and wait till 1.50 am,?
Do I turn off the tracking,(sidereal )leave it on ?
Thank you
Mark

If you click on the 'Planetarium' tab of that site you mentioned (in-the-sky.org) it will show you the comet's position for any time of night, the coordinates are taken from the minor planet centre so it should be as reliable as Stellarium.
Best of luck, hope you don't have the scattered clouds we've got down here in Limerick!

It's said to be around 8.6 mag now and fading although I thought it was brighter (ignore the extremely low magnitudes mentioned on Heavens Above and Starry Night Pro). Weather is bad now so hopefully it will improve during the week.

The magnitude of the comet these days is between 6 and 7. Estimating this with comparing the coma in focus with stars not in focus. Of course, you must never count on values given in software or on simulation sites, these are calculations from universal predicted efemerides.
+7 seems to be the current estimate per an average of binocular observations (between 6.8 and 7.2) in various countries over the past few days and this ties in with figures given by the BAA Comet section and S&T, who both say +7. Could be late this week before the weather clears again and we get another look so will probably have faded a bit by then.

So I just had a look at it here with my 12" and its a fairly non-descript fuzzy blob, usual run of the mill comet with no tail.
although there is a nice ~mag7 yellow star about 4 arc mins away that puts a little colour in the frame...
turned into a nice night, got in a few globulars, the ring nebula and a number of nice doubles before I got tired and turned in.
