Good conditions. I find I am getting a diagonal streakiness in the sharpened images from this camera,which I cannot explain. 
It does not correspond to pixel columns.

Please find attached two Jupiter drawings from last night.  The seeing was superb- around AI-II for most of the time I was observing the planet; the image 'rock steady' in the eyepiece.  So much detail was visible on the disk it is unlikely I was able to record it all.  We've not had conditions that good in Leicester for a long time,this was probably my best view of the planet in this apparition!

Drawing 1:  At these longitudes,the following points were noted:

In the far south the SSTB and STB seemed fairly well defined.
Oval BA was very hard to pick up,and no trace of colour was detected.  It was only the dark greyish boarder which hinted at its position.
SEB broad with some interesting structures present.
EZ seems now to be rather devoid of any strong festoons.
NEB not as broad as the SEB but quite a bit of activity present in the form of lighter sections and fine delicate dark brown lines and sections.
Strong hints of bluish material in the NTropZ
NTB almost completely absent
NNTB dark and well defined,although its northern boarder was somewhat irregular rather than uniform.

Drawing 2: At these longtiudes,the GRS is visible.  Points of interest:

SSTB osberved,STB contains a number of darker sections and some white ovals.
STropZ contains some thin darker sections
GRS now quite small but a striking orange colour- a darker core seemed to be present
SEB broad,The SEBs was dark and curves down and under the GRS leaving a brighter RSH.  SEBz also dark,and some lighter sections seem to be visible in the SEBn.
Not much festoon activity in the EZ at these longitudes.
NEB again quite active,e specially long the northern boarder.
NTB vague,but a thin darker section could be made out.
NNTB continues to be well defined,and greyish brown in colour.

The seeing was fair. The night was temperate with no humidity but with occasional wind gusts.
I can see a dark spot in the NEB near the CM. The EZ presents several dark festoons.
The SEB looks quiet in this area. The white spots surrounding the GRS ghost are bright in methane band.

Good steady conditions early evening on Sunday here
