Hi Chris,

I would have had an image of 2009P1 but had a problem with my laptop during the imaging survey. Later this week there should be some more clear weather so will have to wait until then.

I did a quick magnitude estimate from CCD images:

C/2011 C1 McNaught
2011 Apr 12.75 UT; m1= 10.0; Dia= 3.5’; DC= -; 20cm SCT, f:2.1 (CCD - unfiltered)

No way in the world this comet is mag 8.6 though.....

Terry
