This I can confirm. Astrometrica updated with elements from the MPC showed dRA +2.8' and dDe -1.3' for all C/2011 L4 positions on my images from 2012 05 14. ...
Thanks everyone for the feedback. It appears that Terry hit the issue right on the head. I was using the MPC's ephemeris service, but when I just now compared...
