We present a report on the 2011/12 apparition, apart from the final few weeks when great changes began. The planet was largely quiet; the SEB was recovering after the Revival of 2010/11, while the NEB was narrowing in preparation for what would turn out to be a spectacular Revival starting in 2012 March.  Nevertheless, the improved quality of images allowed us to survey the planet in detail and to detect many interesting phenomena.

The report consists of the following files which can be downloaded below:
