Here's my data from 25 November 2012 - taken with my new ST-10XME:
B - 12.86
V - 12.60
R - 12.67
I - 13.26
This is calibrated.
It looks to me like the V, R and I are dropping but the B is diminishing at a slower rate.
I need to get my 13 year old son to teach me how to use Excel to plot this now.
Overcast in Sydney again - I expect no more clear skies till Friday now
