I made an observation of Jupiter on April 4, 2006 at 01:20 U.T. under average seeing conditions (5-6/10. moments of 6-7/10). The North Equatorial Belt (NEB) and the South Equatorial Belt (SEB) displayed a wealth of structure as depicted. Time constraints did not allow me to make a color observation. I welcome any comments that you may have on my observation.
Date (U.T.): April 4, 2006
Time (U.T.): 01:20
L1 046.9, L2 232.1, L3 001.3
Instrument: 9-inch (23-cm) F/13.5 Maksutov-Cassegrain
Magnification: 248x and 271x
Filter: Klee OPS Barlow
Seeing (1-10): 5-6 (moments of 6-7), Antoniadi (I-V): III
Transparency (1-6): 5
Notes:
South Polar Region (SPR): Appears dark to dusky (3-4/10) and mottled.
South South Temperate Belt (SSTB): Appears dusky (4/10) and diffuse.
South Temperate Zone (STZ): Appears bright (7/10) and thin.
South Temperate Belt (STB): Appears dark to dusky (3-4/10) with three very bright (8/10) ovals within it (central oval timed at 230.3 (L2)/ 359.5 (L3)).
South Tropical Zone (STrZ): Appears bright (7/10) without any other detail visible within.
South Equatorial Belt (SEB): Appears dark to bright (3-7/10) and complex. A bright (7/10) scalloped preceding half is noted whereas the following half contains a dark (3/10) central bar.
Equatorial Zone (EZ): Appears dull to bright (5-7/10) with a central, dull (5/10) band (EZB) connecting to dusky (4/10) projections from NEB-S festoons.
North Equatorial Belt (NEB): Appears dark to dull (3-5/10) with dark to very dark (2-3/10) blue festoons over it's southern border (NEB-S; central festoon timed at 033.4 (L1)/ 348.0 (L3)). The northern border (NEB-N) appears irregular. A central thin, bright (7/10) zone is noted as well.
North Tropical Zone (NTrZ): Appears bright (7/10) without any other detail visible within.
North Temperate Belt (NTB): Appears dark (3/10) and thin.
North Temperate Zone (NTZ): Appears shaded (6/10) and thin.
North Polar Region (NPR): Appears dark to dull (3-5/10) and mottled.
Satellite: Callisto (IV) appears north and following the planet.
The best of luck imaging and observing Jupiter.
