I have made an observation of Jupiter on January 7, 2003 (05:50 U.T.). Much detail was noted over the disk. I hope that you enjoy it. Any comments would be welcome. The best of luck in your own observations.
Date (U.T.): January 7, 2003
Time (U.T.): 05:50
L1 347.3, L2 197.5, L3 012.1
Instrument: 9-inch (23-cm) F/13.5 Maksutov-Cassegrain
Magnification: 248x and 352x
Filters (Wratten) 23A, 30, and 64
Seeing (1-10): 5-6 (moments of 7/10), Antoniadi (I-V): III
Transparency (1-6): 6
Transit Observation:
06: 05 U.T. L2 206.5 L3 021.2 DC Barge (Center of dark barge over NEB-N)
Remarks:
South Polar Region (SPR): Appears dusky (4/10) without other detail noted within.
South South South Temperate Zone (SSSTZ): Appears thin and shaded (6/10).
South South South Temperate Belt (SSSTB): Appears thin and dull (5/10).
South South Temperate Zone (SSTZ): Appears thin and shaded (6/10).
South Temperate Zone (STZ): Appears bright (7/10), but no other detail within.
South Temperate Belt (STB): Appears dark (3/10) whereas the preceding half appears deviated to the south and the following half is parallel to the rest of the belts.
South Tropical Zone (STrZ): Appears bright (7/10) containing a very bright bi-lobed oval (8/10) adjacent to the STB and another very bright (8/10) oval over the SEB-S.
South Equatorial Belt (SEB): Appears dark (3/10) with a bright (7/10) rift or zone visible within the SEB adjacent to it's southern border preceding the CM then bisecting the SEB following the CM. The southern border (SEB-S) appears dark to very dark (2.5/10) and irregular (or undulating) with possible condensations.
Equatorial Zone (EZ): Appears bright (7/10) containing a dull (5/10) Equatorial Band (EB) with northern and southern projections (appearing to connect to two prominent NEB-S festoons).
North Equatorial Belt (NEB): Appears dark to dusky (3-4/10). Two prominent festoons are noted along the southern border (NEB-S) preceding and following the CM. Two very dark (2/10) barges (or rods, small and large) are noted preceding the CM and another large, very dark (2/10) barge following the CM along the northern border (NEB-N).
North Tropical Zone (NTrZ): Appears bright (7/10), but without any detail noted within.
North Temperate Belt (NTB): Appears faded from previous apparitions (5-6/10 versus 3-4/10). The central portion being more prominent whereas the preceding and following ends appearing to disappear.
North Temperate Zone (NTZ): Appears bright (7/10), but no other detail noted within.
North Polar Region (NPR): Appears dusky (5/10) with dusky (4/10) condensations visible towards the following limb and a dusky (4/10) hood (or northern limb).
