Roger go into the extras menu in guide and select "edit comet data".

select LINEAR 2001 A2.

change the absolute Magnitude (H) value to H-5 .

that should make the value closer to what you are observing. But note what
has been said about the outburst. You can always change the value back to
its original value later or load in an updated set of comet orbital
elements from the MPC
