All images are made with a self made CB245 CCD camera, mounted on a 80 mm f/15 refractor. I used oculair projection to enlarge the images. All are processed with unsharp masking. North is on top.

05 Dec 1999

This image has an integration time of 0.1 s.

15 Nov 1999

The images have integration times of 0.1 or 0,15 s. A lot of features can be seen on this images, especially around the northern dark belt. Just to the left of the planet, the moon Ganymede moves out of the planets shadow. Io is at the right side, and moves fast. The moon Europe (far left) was only captured by the first 2 images. It felt outside the CCD chip on the last 2 images.

31 Oct 1999

The images have integration times of 0.1 s. The northern dark belt, of the upper image, shows a white spot. It moved to the right in the lower image, by Jupiters rotation.

27 Oct 1999

This image has an integration time of 0.15 s.

23 Oct 1999

The images have integration times of 0.1 - 0.15 s. A lot of features can be seen. The first image shows the GRS (Great Red Spot) very well. Look also at the movement of the moons.

13 Oct 1999

Both images have integration times of 0.2 s. A few belts (dark structures) can be seen on the planet this year. The upper image just shows the 'Great Red Spot' (GRS) at the left limb of the planet. In one half hour (lower image), the GRS and other features are moved to the right, because of the rotation of the planet. In the upper image, you can also see the moon Io, just to the right of the planet. In the lower image, it has just disappeared in the shadow of Jupiter. This is called a Moon eclipse. Moon eclipses are very common on Jupiter.
