I made an observation under good seeing conditions (7-8/10). Much detail was noted across the jovian disk which made it difficult to record it completely. The North Equatorial Belt (NEB) was again noted to be very active as shown. I welcome any comments on my observation.
Date (U.T.): April 27, 2004
Time (U.T.): 04:10
L1 182.5, L2 001.3, L3 302.6
Instrument: 9-inch (23-cm) F/13.5 Maksutov-Cassegrain
Magnification: 258x and 388x
Filters: None (IL)
Seeing (1-10): 7-8, Antoniadi (I-V): II
Transparency (1-6): 6
Notes:
South Polar Region (SPR): Appears dark to dull (3-5/10) and mottled.
South South Temperate Zone (SSTZ): Appears bright (7/10) and thin.
South South Temperate Belt (SSTB): Appears dull (5/10) and thin.
South Temperate Zone (STZ): Appears bright (7/10) and broad.
South Temperate Belt (STB): Appears dark to dusky (3-4/10) and broad. No ovals are noted within it at this time.
South Tropical Zone (STrZ): Appears bright (7/10) with a central dull (5/10), thin band.
South Equatorial Belt (SEB): Appears dark to dusky (3-4/10) with a thin, bright (7/10) and undulating zone (SEBZ) at it's center.
Equatorial Zone (EZ): Appears shaded to bright (6-7/10) with dusky to dull (4-5/10) condensations and projections within it.
North Equatorial Belt (NEB): Appears complex with dark to dull (3-5/10) sections containing bright (7/10) ovals and rifts within it. Very dark (2/10) festoon bases are noted along the southern border (NEB-S). Dark (3/10) projections are noted along the northern border (NEB-N; one is noted on the CM at L2 001.3 (L3 302.6).
North Tropical Zone (NTrZ): Appears bright (7/10) with very bright ovals noted along the NEB-N.
North North Temperate Belt (NNTB): Appears dusky (4/10) and broad.
North North Temperate Zone (NNTZ): Appears bright and thin.
North Polar Region (NPR): Appears dull to dark (3-5/10) and mottled.
The best of luck in your own observation and imaging of Jupiter.
