I made an observation of Jupiter on May 8, 2003 (03:00 U.T.). I noted much
detail across the disk, especially over the South Tropical Zone (STrZ) and
Equatorial Zone (EZ). I welcome any comments on my observation.

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) with two dark
(3/10) projections noted along it's northern border extending into the South
Tropical Zone (STrZ).
South Tropical Zone (STrZ): Appears bright (7/10) with a dark (3/10)
condensation within it which appears connected to a dull (5/10), thin band.
South Equatorial Belt (SEB): Appears dark (3/10) and separated by a bright
(7/10) and thin SEB zone (SEBZ).
Equatorial Zone (EZ): Appears bright (7/10) with a diffuse dusky to dull
(4-5/10) band (EZB). A dark (3/10) condensation appears over the preceding
EZ within the EZB.
North Equatorial Belt (NEB): Appears dark (3/10) with very dark (2/10) blue
festoons noted along it's southern border and very dark (2/10) barges along
it's northern border.
North Temperate Zone (NTZ): Appears bright (7/10) without the presence of
the North Temperate Belt (NTB).
North Polar Region (NPR): Appears dull to dusky (4-5/10), but without any
detail visible within.

Dear friends,
Very low transparency though the seeing was pretty good.
Can only seee Jupiter, Sirius and Moon on the sky.
I had to gain 80% for this Jupiter and extended the exposure duration to 2 mins in order to increase the S/N rato.

The very faint oval BA can be seen near CM. Also quite active festoons in EZ. The NTrB is visible.
Kind Regards,
