I've been watching Lulin, on and off, since around the 12th Feb.
Every night it's been a little further on, and higher up (shame about the cloudy nights which have spoiled the sequence

Past it's best now, but still fairly easy to spot as a hazy patch in binoculars.
For the benefit of anyone who uses Stellarium - the free planetarium software......
www.stellarium.org
Here's how to add Comet Lulin, so it shows you where to find it......
Locate the '.ini' file called 'ssystem'
It's under the filepath... Program Files - Stellarium - Data
First - copy this file, and paste a copy somewhere safe on your hard-drive, as backup.
Now - open the original 'ssystem' with 'notepead'....
Then copy and paste the following lines of text, at the bottom, after the other text.
[Lulin]
name = Lulin
parent = Sun
radius = 1000
oblateness = 0.0
halo = true
color = 0.7,1.4,0.7
tex_halo = star16×16.png
tex_map = nomap.png
coord_func = comet_orbit
orbit_TimeAtPericenter = 2454842.15
orbit_PericenterDistance = 1.212267
orbit_Eccentricity = 0.999986
orbit_ArgOfPericenter = 136.8660
orbit_AscendingNode = 338.5392
orbit_Inclination = 178.3736
lighting = false
albedo = 1
sidereal_period =
Close notepad, and save the changes.
Now - when you start up Stellarium - Comet Lulin will be highlighted
**NOTE**
The stated magnitude (brightness) is a LOT brighter than Lulin really is.
This is deliberate, so that Lulin will be obvious, and automatically highlighted by Stellarium. Position will be correct though.
Any problems, simply paste your saved copy of 'ssystem' back into the 'data' folder, and overwrite the one you altered.
Also - when Lulin has faded away - doing the same will remove the Lulin entry from Stellarium's database.
edit...
For Mac or other OS users - I'm sorry, I don't know the filepath for finding the 'ssystem' file - but editing in the same lines of text will work the same as it does for Window$ machines.
