Is it possible to get category description in a module position

[wonderland]

There is a parent category description in category view (

Code Select Expand

<?php echo $this->category->category_description; ?>)

I was wondering is it possible to get this description in a module position ? I would really need this for my template.

I tried adding

Code Select Expand

<?php echo $this->category->category_description; ?> in a php code module, but I got "Fatal Error:Using $this when not in object context" When I tried do that.
