Does anyone have the right data so I can input into Stellarium? Have already sewarched a bit, but cant find it.

This comet is much brighter than anticipated, and is currently about mag 10 -11 (thanks Rob).

Now I have to remember how to put that data in. :question:

What version of Stellarium is it Liz? 0.10.6.1 can load comets itself.
Configuration->Plugins->Solar System Editor->configure
Solar System tab
"Import ..." button
Comets
Download ...
Select bookmark -> MPC's list ...
Get ...
Mark all (or just the ones you want)
Add objects

Or add these lines:

radius = 19
albedo = 0.15
absolute_magnitude = 11.3
absolute_magnitude = 18.1
type = comet
at the bottom of this data for older versions:

[McNaught_C2011_C1]
# Data taken from JPL/HORIZONS
# correct for the specified time frame:
# Start Time : A.D. 2011-Mar-19 00:00:00.0000 CT
# Stop Time : A.D. 2011-Mar-19 00:00:00.0000 CT
