Hi Malc

The AAVSO updated the original chart a few days ago and some of the comparision stars around 11th magnitude were the ones that changed. If you downloaded the chart a while ago, it may pay to download it again. There is a 11.1, 11.4 and 11.6 mag comparision stars on the latest chart which is what I have been using.

Regards
Andrew
