I made an observation of Jupiter on November 21, 2010 (00:06 U.T.) under good seeing conditions (6-7/10). The Great Red Spot (GRS) was visible on the central meridian (CM). I welcome any comments on my observation.

Date (U.T.): November 21, 2010
Time (U.T.): 00:06
L1 282.7*, L2 158.3*, L3 20.3*
De 2.0*, Ds 2.3*, -2.6m, 43.9” (Equatorial)
Instrument: 9-inch (23-cm) F/13.5 Maksutov-Cassegrain
Magnification: 310x
Filters: None
Seeing (1-10): 6-7, Antoniadi (I-V): III-II

Notes:
South Polar Region (SPR): Appears dark to dusky (3-4/10) and mottled. Irregular dark (3/10) condensations and shaded to bright (6-7/10) ovals/streaks are visible within it.
South South Temperate Zone (SSTZ): Appears to contain a very bright (8/10) oval preceding (p.) the CM and a bright (7/10) section following (f.) the CM.
South South Temperate Belt (SSTB): Appears thin, irregular, and dusky (4/10).
South Temperate Zone (STZ): Appears dusky to shaded (4-6/10). Oval BA appears dusky (4/10) and orange-reddish with a dark (3/10) rim p. the CM.
South Temperate Belt (STB): Appears broad, irregular, and dark to dusky (3-4/10). Dark to dusky (3-4/10) projections extending into the South Tropical Zone (STrZ) are noted over the northern border south of the Great Red Spot (GRS). The following (f.) half of the belt appears to deviate towards the south with a bright (7/10) zone and an irregular, dark to dusky (3-4/10) belt noted as well.
South Tropical Zone (STrZ): Appears bright (7/10) and without any other detail visible within.
Great Red Spot (GRS): Appears dusky to shaded (4-6/10) with a bright (7/10) core and a dusky (4/10) rim. The preceding end is located at 169.8* L2 (11/21/2010 at 23:55 U.T., or 31.8* L3), center at 158.3* L2 (20.3* L3), and following end at 165.0* L2 (26.9* L3). The bright (7/10) core was irregular and mixed with dusky to dull (4-5/10) sections.
South Equatorial Belt (SEB): Appears pastel reddish-pink color and dull (5/10) with dusky to dark (3-4/10) irregular streaks. The Red Spot Hollow (RSH) appears dark to dusky (3-4/10) and is re-developing.
Equatorial Zone (EZ): Appears shaded to bright (6-7/10) with bluish-gray irregular dusky (4/10) streaks and festoon projections extending from the southern border of the NEB within it.
North Equatorial Belt (NEB): Appears broad and dark to dusky (3-4/10) with dark (3/10) condensations and bright (7/10) streaks within it. Dark to dusky (4/10) bluish-gray festoon bases are noted along the southern border.
North Tropical Zone (NTrZ): Appears shaded (6/10), and no other detail is visible within.
North Temperate Belt (NTB): Appears thin and dusky (4/10) with a dark (3/10) condensation noted f. the CM (preceding end at 169.8* L2 (31.8* L#), center at 172.8* (34.8* L3), and following end at 175.8* L2 (37.8* L3)).
North Temperate Zone (NTZ): Appears thin and shaded (6/10).
North North Temperate Belt (NNTB): Appears dark to dusky (3-4/10) and no other detail is visible within it.
North North temperate Zone (NNTZ): Appears thin and shaded (6/10).

Carlos,

A beautiful pair of sketches with an amazing amount of detail. From what you have recorded in your report there was very much to record and see.
This had to be a very satisfying observing session.
Superb post.

Frank :)

Frank,

It was quite a sight to see the Great Red Spot (GRS) on the CM so prominent and all of the other detail noted. The hard part was recording all the detail as accurately as possible. The best of luck in your own observations of Jupiter.

Carlos,

Beautiful work on the King (and I'm sure a lot of it with all that detail rendered). Very striking with the GRS dead center looking back at us--who's observing whom? :)

Thank you all for the kind compliments on my latest observations of Jupiter. I was fortunate to catch the Great Red Spot (GRS) on the CM. I hope to view the SEB Revival soon. The best of luck in your own observations of Jupiter.
