2003/2004 apparition images
 |
GRS has passed transit. Callisto has started transit of the jovian surface. Callisto has a lower surface brightness than jupiter so it appears dark during transit.
Date: 13th Apr, 2004 15:11UT |
 |
GRS in transit. Callisto is near the lower right limb and entering transit soon. Visually the GRS appears as very bright orange. Some hints of surface features on Callisto in this image.

Comparison of Toucam in Normal and RAW color
mode. |
 |
My first image for apparition of 2003-2004. First attempt with Toucam in color RAW mode, this results in a reduced noise in the final image hence retaining the low contrast features.

2002/2003 apparition images
 |
This image is taken when jupiter altitude is only 55 degs. Seeing is very poor at this altitude. Note the white oval at the SPR.

This is one of my very best shot to date consider that jupiter is only 39" in size. Taken in 7-8/10 seeing. GRS rotating into view from the following limb. Note the dark spot on the north hemisphere. The jetstream spot seems less obvious now after contacting the GRS
Date: 17th Apr, 2003 13:21UT |
 |
Poor seeing this evening. The jetstream spot on SEB apparently has broken into two and one them has already contacted the GRS.
Date: 13th Apr, 2003 12:36UT |
 |
Some thin clouds moved in and seeing has degraded much for this image. The GRS has rotated near to the CM. The jetstream spot on SEB is approaching the GRS. Note it's position on the 19th Mar image.
Date: 10th Apr, 2003 13:44UT |
 |
The GRS is near the following limb, the SSTB ovals are clearly seen. The NTrB can be seen here as a grey line just north of the NEB. Fine details are noted over the whole visible disc. Note the changes in the relative position of the features compared to the 19th Mar image.
Date: 10th Apr, 2003 12:56UT |

The GRS is just at the very edge of the following limb (look very carefully), the SSTB ovals are clearly seen. The NTrB can be seen here as a grey line just north of the NEB. Fine details are noted over the whole visible disc.
Date: 19th Mar, 2003 14:01UT |

was seen in the images on 7th March. The dark streak south of the GRS has broken
up further.

longtitude.

Io is in transit, the dark polar
region could be seen against the jupiter background. You can compare
the details with the 10th Mar shots and see the changes in details.
The NTrB can be seen here as a grey line just north of the NEB.

This is a larger processed version
of the io transit shot, you can compare the difference with the
14:39UT image. The dark polar
region could be seen against the jupiter background.. You can compare
the details with the 10th Mar shots and see the changes in details.
The NTrB can be seen here as a grey line just north of the NEB.

Part of the remaining weaken
NTB can be seen just rotating into view at the following limb.Note the
whole stucture of the SEBz and dark matter along the STB
Date: 10th Mar, 2003 15:44UT |

Another image from 10 Mar, with
the rest of the 3 images you can see the rotation of jupiter.
Date: 10th Mar, 2003 15:24UT |
 |
My best shot to date. This image
is about 7mins apart from the earlier on, however the features (GRS)
near the limb appears to "move slower" compared to the
features near the CM. Compare the details carefully to see the
rotation.
Date: 10th Mar, 2003 15:07UT |
 |
GRS is near the preceding limb. Note the blue
festoon that stretches from the NEB to SEB. The NTrB which is not
visible normally can be seem as a grey belt just north of the
NEB.

GRS is in transit. The dark matter around the GRS has changed compared to what
was seen in the images days earlier. The dark streak south of the GRS has broken
up further. The NTB remains weak and segmented.
Note the long dark streak and white oval at the NNTB as well as
it's changes compared to the images earlier.

Ganymede appears near the preceding edge of the disk.
Much details were noted over the disk. Some tiny white spots were observed near the NNTB, their rotation can be follow in the 3 images. The NTB remains weak and segmented, the NEB appears dark, with a dark festoon near the CM in the 15:00UT image. The SEB appears to be bisect by a thin bright zone.

Much details were noted over the disk, the NEB appears dark, a bright zone was observed in the NEB which is near the CM in the 16:17UT image. The region of the SEB preceding the GRS appears dark for it's southern border. A dark streak was observed at the NNTB which is near the CM in the 16:17UT image and appears to be breaking up.

Io can be seen in transit across jupiter, the dark contrast of it's two poles can be seen easily.
Oval BA is near the preceding limb. The NTB is weak and only traces can be seen in the image. Note the fine details/ovals in the NEB,SEB and the polar regions.

Lunar New Year Jupiter! Joint effort with Hong Kong Planetary master Eric Ng Part of SEB Disturbance and Oval BA can be seen on these two images. As transparency at that night was very low, the "ring" effects can be found near the edge due to insufficient dynamic range and under exposure.
Date: 31 Jan, 2003 14:58. 18:15UT |
 |
Notice the fine details on the SEB and NEB. The NTB is
weak and barely visible.

First light jupiter image with the mewlon 250. This
images tells me I've not made the wrong choice for my planetary scope.
