Hi Bill,

when Guide 9.0 DVD finally had passed customs (without fee) I installed it
and saw I would be pretty content with your great work - thank you a lot.

One thing puzzled me though:
Guide9 displays comet Garradd with mag 12.7 in comparison to Guide8
which displays it with mag 7.7 - what should be the right magnitude.

When comparing the entries in the MPCORB files

30.09.2011 (Guide8):
Garradd (C/2009 P1) 23.6755 12 2011 0.0
1.550564 1.001011 106.1774 90.7454 325.9972 2000.0 4.0 4.0
MPEC 2011-S56

30.11.2011 (Guide9):
Garradd (C/2009 P1) 23.6755 12 2011 0.0
1.550564 1.001011 106.1774 90.7454 325.9972 2000.0 9.0 4.0
MPEC 2011-W48

one can see the dufference, so it's not a matter of Guide.

Is this all right or should'nt be the actual magnitude of comet Garrad
7.x instead of 12.x? Perhaps you can shed some light on this?

CS and many thanks,
Rolf Stadelmaier
