Comet Linear 2002 T7 not doing as well as expected was created by gnason
Personally, I've found this comet to be less of an observing experience than I expected from earlier predictions. Many people have even found it difficult to see despite its easy location. These comments from John Bortle explain the reasons.

"I thought it might interest the group to hear about what recent data
indicates regarding the current activity and likely future
development of this comet.
Contray to what info on several websites are touting, Comet LINEAR is
not doing well at all and is progressively falling further and
further behind its brightness predictions. The comet's lightcurve
began to nose-over at the beginning of January and during February it
has become almost flat, hardly brightened at all in either apparent
or heliocentric magnitude. Over the past 30 days its lightcurve can
be represent quite well by the formula:
m1 = 5.0 + 5 log delta + 2.5 log r
indicating that it is brightening at a much slower rate than ever a
simple reflecting body would be expected to.
Sadly, this is just the scenario played out by so many other "new"
comets (remember Kohoutek and Austin?). If LINEAR's development
remains as stunted as it currently appears, the comet will prove a
rather unimpressive sight as it passes near Earth in mid May. No
Great Comet this, I'm afraid. Hope for a better show from Q4.

Expecting a comet to give a great show is like going on a solar eclipse expidition and been clouded out, I'd never get my hopes up until I can see it for myself.

Mmmm, I too was looking at this one last week, I found it quite hard to find in Binoculars, through the scope, it just looked like a bright Messier object. Hopefully it will pick up :
