      #3963996 - 08/04/10 04:22 PM Attachment (51 downloads)

I made an observation of Jupiter on August 3, 2010. I was able to make out a good amount of detail over the jovian globe. I was using a new Pentax XW 10 mm eyepiece. This is a phenomenal eyepiece with outstanding transmission, sharpness, and contrast.

Date (U.T.): July 29, 2010
Time (U.T.): 05:00
L1 295.0*, L2 326.6*, L3 157.9*
Diameter (Equatorial): 45.1"
Instrument: 9-inch (23-cm) F/13.5 Maksutov-Cassegrain
Magnification: 129x and 310x
Filters: None (IL)
Seeing (1-10): 6-7, Antoniadi (I-V): II
Transparency (1-6): 4

Notes:
South Polar Region (SPR): Appears dark to dusky and mottled (3-4/10).
South South South Temperate Zone (SSSTZ): Appears dusky to dull (4-5/10) and mottled.
South South South Temperate Belt (SSSTB): Appears dusky (4/10) and irregular.
South South Temperate Zone (SSTZ): Appears dusky (4/10) with shaded to bright (6-7/10) small ovals/rifts within it.
South South Temperate Belt (SSTB): Appears broad and dusky (4/10).
South Temperate Zone (STZ): Appears shaded to bright (6-7/10) with bright (7/10) sections separated by dusky to dull (4-5/10) columns.
South Temperate Belt (STB): Appears broad and dark to dusky (3-4/10). The following portion of it appears to diverge towards the north. It contains dark (3/10) condensations within it.
South Tropical Zone (STrZ): Appears bright (7/10) with no other detail visible within it.
South Equatorial Belt (SEB): The thin, dull (5/10) northern border of the SEB is visible.
Equatorial Zone (EZ): The EZ appears to contain a complex network of bluish-green condensations and streaks (lace-type). Bright (7/10) areas are noted within the darker areas.
North Equatorial Belt (NEB): Appears dark to dusky (3-4/10) with dark (3/10) condensations noted within it. A bright (7/10) oval is noted over it's preceding end and bright (7/10) rifts are also noted over it's midsection. The southern border contains bluish-green festoons which project into the EZ.
North Tropical Zone (NTrZ): Appears bright (7/10) without any other detail visible within it.
North Temperate Belt (NTB): Appears dark to dusky (3-4/10) and bisected. The southern component appears to contain dark (3/10), elongated condensations.
North Temperate Zone (NTZ): Appears thin and shaded to bright (6-7/10).
North North Temperate Belt (NNTB): Appears dark to dusky (3-4/10) and broad.
North Polar Region (NPR): Appears dark to dull (3-5/10) with dusky (4/10) mottling noted within.

Carlos,

Very, very impressive sketching of planet Jupiter.
In addition to the beautiful renderings your notes make this a complete package of observation.
Stunning!

Thank you all for the compliments on my latest observation of Jupiter. I was impressed by the amount of detail visible over the disk of Jupiter. The blue streaks over the Equatorial Zone (EZ) were subtle but striking. The best of luck in your own observations of Jupiter.
