Dear Jupiter observers,


Attached is the jupiter image from 13th April 2003.


Seeing was pretty bad as the it has rained this afternoon but it suddenly cleared up just after sunset.


The jetstream spot seems to have broken into two parts and one part has already come into contact with the GRS.

Dear all,


I had some free time before imaging this evening so I processed some images

which are long overdue.

I've tried to achieve a more "natural" look to the images.

Subject: jupiter 15th March 2003 - 1447UT


Seems like nowadays the trend is to get the big jupiter, being caught in the

situation, I've no choice but to follow the trend.


The is an additional image from 15th March, after the first two that I posted

earlier on.

Subject: jupiter image 19th March 2003 - lucky shot.


Dear everyone,


Attached is the jupiter image from this evening 19th March 2003.


For this image, I had to fight not against the seeing but against the clouds. It was clear the whole day and while I was setting up, clouds started to roll in from the western horizon, as jupiter had not cleared my home building's obstruction I could not start imaging. Finally when my scope is still 50% blocked by the building I took this image while the clouds are still "inches" away from blocking jupiter. Seeing looks good and getting 50% blocked doesn't seems to affect the resolution too much.


I was very happy with the processed image.


Seeing about 5-6/10, the GRS has not come into view yet but you can see the dark matter circulating near at the preceding side of the GRS on the very edge of the following limb. Very interesting.

Dear Jupiter observers,


Attached is the jupiter image from 17th April 2003


The 1425UT image is taken with jupiter at 55 degs and the seeing is not very good and makes getting image pretty difficult. I guess it is still possible to get something useful at this altitude.


It seems like the jetstream spot is less obvious today.


I will go thru the rest of the AVI and see if I can get some view of GRS/jetstream spot.
