Peter,

Thanks for the image obtained under difficult circumstances.

Martin Mobberley got 10.7 on March 9.78 and visual estimates on COBS are
all around 10.0 now with one bright outlier. It probably won't get much
brighter through March and April. At least it will become easier for us
to observe from the UK over the next few weeks.

Nick.
