相変わらずの単身赴任生活で、観測地は堺です。

超多忙のため、しばらく休業中でしたが、
ようやく、復活できました。
少々ブランクがありましたが、
テクニックは忘れてはいませんでした。

A very poor morning, with focusing difficult to impossible; intermittent clouds and
unsteady air at its worst.  Nonetheless, the GRS was measured at CM 98.8 (II) at center.

I made an observation of Jupiter on April 17, 2005 at 04:40 U.T. using a 9-inch F/13.5 Maksutov-Cassegrain.
Much detail was noted over the disk, especially the NEB and SEB.
Io and Callisto were visible preceding and following the planet, respectively.
I welcome any comments on my observation.

Date (U.T.): April 17, 2005
Time (U.T.): 04:40
L1 060.7, L2 053.6, L3 090.6
Instrument: 9-inch F/13.5 Maksutov-Cassegrain
Magnification: 248x
Filters: None (IL)
Seeing (1-10): 5-6, Antoniadi (I-V): III
Transparency (1-6): 5

Notes:
South Polar Region (SPR): Appears dark to dusky (3-4/10) and mottled.
South Temperate Zone (STZ): Appears bright (7/10) and thin.
South Temperate Belt (STB): Appears dark to dusky (3-4/10) with an irregular northern border.
The following half appears deviated towards the south.
South Tropical Zone (STrZ): Appears bright (7/10) without and other detail noted within.
South Equatorial Belt (SEB):  Appears dark to dusky (3-4/10) with an bright (7/10), irregular zone over it's mid-section.
Equatorial Zone (EZ): Appears bright (7/10) with dusky to dull (4-5/10) bands over the middle of the zone.
North Equatorial Belt (NEB): Appears dark to dusky (3-4/10) and mottled.
A bright (7/10) rift is noted originating over the southern border of the preceding half and extending
north and then diverting towards the following half (just within the northern border). Dark (3/10) blue festoons
were noted along the southern border (NEB-S).
North Temperate Belt (NTB): Appears dark (3/10) and thin.
North Temperate Zone (NTZ): Appears bright (7/10) and thin.
