Lovejoys path

There are two ways to plot the path of a comet, RA/Dec and Alt/Az.
RA/dec shows the position with respect to the stars.
Alt/Az shows the altitude with respect to the horizon.
Attached are SkyMapPro maps for both methods, looking SSE at 5am AEDT from latitude 29S.
The 6% phase Moon will be 20 degrees north of Comet Lovejoy tomorrow morning.
