Subject: Jupiter images (Jan 28th, 29th.)

Hi all,

Here are some Jupiter images from Jan 28th and 29th.
All were obtained with the ST-5c, apart from the
"rgb.jpg" image from the 29th, obtained with the
webcam. I think i prefer to use the ST-5c, as its
images have better S/N ratio, which shows well in the
many small spots that can be followed + the processing
is much less tiring!.

I also include a projection map showing most of the
Planet from the images. Its interesting to note how
the NTB has now completely faded away around the GRS
longitude, while some remnant of it remains toward
Oval BA. The dusky grey North Tropical Band can also
be followed around the Planet. Also note some SEBs
jetstream activity on the 29th.

The weather has now become very windy, so its unlikely
more will be possible until my weekend excursion to
the observatories here. 

Best Wishes

Damian
