What do you mean by that it's visible at equatorial lattitude at 12.20 noon ?

Pls note what can be seen from equator from the following site

Kochu/11-1-07

The time 12:20 is when the comet is highest in the sky. Actually now as long as you have the sun high up in the sky, you got comet McNaught beside the sun.

This is the brightest comet in the last decade!!! We should try catch it as long as there is a possiblity, even daytime obs!!!

I don't have access to a sky chart now - is the comet to the east or west of the sun? We might be able to catch it during sunrise/set?

Here is a sky map for 19:11 Jan. 14th, at which time the sun just set, the comet is 5 degrees above the horizon. At daytime, around noon, the comet will be to the left of the sun.

It is very possible that this comet becomes the brightest comet in the past thirty years!!! We can't miss it!!!

It looks very dangerous to observe!

Where can I have the data to put in to my Starry Night?

Yeah, that's why I suggest that we observe at Science Centre where there is an accurate GOTO scope

what do you mean where to put the data? most often i will do an update on the starry night database then go forward to that day 14th Jan and using the list of all the objects then find where the comet is... not sure if its totally acurate tot... i think it should be, i use this method often to estimate the location of whatever event or objects that might appear above us...

Here is a list of bright comets since 1935, if comet McNaught brightens up above mag. -4, it will be the second brightest comet since 1935!!!
