コメント：途中から良いシーイングになるかと思われたが、強い風が吹きシーイングが悪くなった。
その後、シーイングが改善されそうになったがダメだった。
ＮＥＢの２５０°（体系III）付近を境として、縞の色が違う。何故だろう。

・観測条件は良くありませんでしたが、SEBの白斑が写ってくれました。
一昨年の場合を調べてみたら、2002/11/28（UT)・・（今回とてもよく似ている）、
12/22（UT)、 2003/01/11（UT)、2003/01/21（UT)などに観測しています。
月惑のホームページから過去の報告を見ることができます。
今回はこの後どんな変化をするのでしょうか、楽しみです。
・NEBのCM付近に大きな変化が見られます。

シーイング、透明度ともに良くないため、詳細は写ってくれなかった。

Seeing=4-5/10 Transparency=4/5
・CM後方でSEBnが淡くなっている、EZn/SEBn disturbanceの活動域と思われる
・CM付近のNEBnの暗斑はNTrZに飛び出している、状況としてはLRSに似ているが赤みはない
・この経度のfestoonは淡く目立たない

I made a Jupiter observation under average to good seeing conditions (6-7/10).
Much detail was noted especially between the SEB and NEB. I welcome any comments on my observation.
Date (U.T.): April 22, 2004
Time (U.T.): 04:45
L1 133.8, L2 350.6, L3 290.6
Instrument: 9-inch (23-cm) F/13.5 Maksutov-Cassegrain
Magnification: 258x and 388x
Filters: None (IL)
Seeing (1-10): 6-7, Antoniadi (I-V): II-III
Transparency (1-6): 4-5 (hazy)
Notes:
South Polar Region (SPR): Appears dark to dusky (3-4/10) and mottled.
South South South Temperate Zone (SSSTZ): Appears thin and bright (7/10).
South South South Temperate Belt (SSSTB): Appears thin and dull (5/10).
South South Temperate Zone (SSTZ): Appears thin and bright (7/10).
South South Temperate Belt (SSTB): Appears thin and dull (5/10).
South Temperate Zone (STZ): Appears thin and bright (7/10).
South Temperate Belt (STB): Appears dark to dusky (3-4/10) and broad.
South Tropical Zone (STrZ): Appears bright (7/10) and it contains a thin, dull (5/10) band across it's center.
South Equatorial Belt (SEB): Appears dark to dusky (3-4/10) with a thin, bright (7/10) zone across it's center (SEBZ).
Equatorial Zone (EZ): Appears shaded to bright (6-7/10) with dull (5/10) projections extending from NEB-S festoons. Very bright (8/10) ovals are noted over it's northern half between festoon bases.
North Equatorial Belt (NEB): Appears dark to dusky (3-4/10) containing bright (7/10) rifts within. A dark (3/10), "hook-like" projection is noted along the northern border (NEB-N) preceding the CM containing a very bright (8/10) oval. Very dark (2/10) festoon bases are noted along the southern border (NEB-S). A bright rift appears to extend from the NEB-N into the center of the NEB following the CM.
North Tropical Zone (NTrZ): Appears bright (7/10) and broad, but no other detail visible within.
North North Temperate Belt (NNTB): Appears thin and dusky (4/10).
North North Temperate Zone (NNTZ): Appears thin and bright (7/10).
North North North Temperate Belt (NNNTB): Appears thin and dusky (4/10).
North Polar Region (NPR): Appears dark to dull (3-5/10) and mottled.
The best of luck to you, your family and on your imaging of Jupiter.
