I sktched on Dec. 31
under excellent sky conditions,along with an intensity estimates template.
Format of the pictures is yyyymmdd_hhmm_name (first four letters of my last
name,in this case).

Here is the text to be published with the pictures:

"2010/12/31 05:35ut
L3=291
Newton 200/6,240-360x
Seeing II (Ant.) Transp. 9/10

Comments:
WS observed for two hours between 4:20-6:20ut,with very good seeing and
transparency,but heavy light pollution. Brightness and contrast much
fainter than described by Gray on Dec. 19; I estimated the intensity of its
parts between 0.5-1.5 (Gray: -1),see attached template with intensity
estimates (BAA scale). They appeared with a distinct white colour,as
apposed to the yellowish disc and the brown bands. Costrast was better with
blue filter,worse with a yellow one,and much worse in red light.

Saturn in not so great seeing conditions,
could salvage one Avi from the bunch I took,The storm is there but the structure is not so good visible.
