It was noticeably dimmer than my last ob on 09/01/2013 UTC.

Wow! You do not know how fortunate you are. I have to travel 70 to 80 miles to get to a blue/green zone. My observations, where my home is located, are from a white zone. At best it is in a red zone on the edge of the white zone.
It appeared to be about 2X brighter than the 8.0M from my backyard green/blue zone.

I did not need averted vision to see the nova or the star just west (above) it. Transparency was very good that night and I don't have any light pollution. Perhaps you had high clouds along with your LP?
I'm no expert and estimating tenths of magnitude visually is tricky and subjective. The nova was definitely brighter than the other star (I'm talking about HIP100536 mag 8.0).
I haven't seen any other mag estimates for 9/7 UT to compare our estimates to. Any around?

What do the numbers on the X axis of your chart mean?

JD on x-axis label stands for Julian Date.

I haven't notice any color except bluish-white, but I usually don't see color very well. Others have reported bluish-white to start, changing to yellowish and now reddish.
Last night (9.22.13) at 120x it appeared yellowish-orange and brighter than its mag 8.0 neighbor star.

With the binoculars, the nova looked almost identical to the 8th mag star and cool white or maybe pale blue. The C8 showed the nova noticeably dimmer than the 8th mag star, but not nearly as dim as any of the 9th mag stars in the FoV. It was nicely framed at 127X and had a golden/yellow color.
