Subject: Jupiter data (Sept 02, 2001)

Hi all,

last night I was a bit "lazy" and slept until Jupiter was almost reaching
the limit horizon of my balcony C11. For this reason I decided to open the
roof observatory and give the 10" LX200 a chance. In the first images the
planet was grazing the roof and only part of the telescope's aperture was
used. Seeing was poor and the sky was getting bright, the latter preventing
the use of the AO-2 in the clear (06:08 UT) and red/blue (06:10 06:14 UT)
images. The AO-2 was always kept in place. The CH4 image is a single 5min
raw, all others are averages of 6-8 raws. Image stabilization was already
defective when the methane image was obtained.

Color and clear filter images show what may be a small NNTB white oval in
the f hemisphere. They also show the large dark spot in the NPR Brian
recently described. A dark spot in IR is just following the GRS (bluish
although less conspicuous in color images and also visible in integrated
light).

Images are presented in 150% of the original sampling.

Regards to all and good observations

Antonio
