Saturn Observation (November 17, 2005)

Posted By Carlos E. Hernandez

I made an observation of Saturn on November 17, 2005 at 06:30 U.T. under average seeing conditions (5-6/10). The South Equatorial Belt (SEB) was prominent (3-4/10) and tan (beige) colored and with an irregular southern border. The Equatorial Zone was bright (7/10) and cream colored. The South Tropical Zone (STrZ) was bright (7/10) and light beige in color. The South Temperate Belt (STB) was thin, dusky (4/10) and light brown in color. The South Temperate Zone (STZ) was bright (7/10) and beige colored. The South Polar Region (SPR) was dusky (4/10), brown colored and mottled with a dark (3/10) central (polar) area. Ring A was dusky (4/10) with a light bluish-gray color (no sign of the Encke minima). Ring B was dusky (4/10) over it's inner half and bright (7/10) over it's outer half. Ring C (Crepe) was translucent and shaded (6/10). Dione, Tethys, and Rhea were noted, preceding to following. I welcome any comments that you may have on my observation.

The best of luck to you and your wife. I look forward to your excellent images.

Lunar-Jupiter Conjunction

Posted By Carlos E. Hernandez

I made a digital painting of a conjunction of the Moon (27.3 days old, Waning Crescent) and Jupiter (separated by approximately 5 degrees) on November 29, 2005 at 11:15 U.T. The nearby clouds displayed a pale orange color that added to the scene. I hope that others were able to observe this event as well.

Lunar-Venus Conjunction (December 4, 2005)

Posted By Carlos E. Hernandez

I made a rendering of the Lunar-Venus conjunction on December 4, 2005 at 22:15 U.T. (05:15 PM EST). The Moon was 3.6 days old and separated from Venus by 3.2 degrees. Thin wispy clouds provided an eerie look to the scene. The palms provided a nice foreground to the scene as well. I hope that you all like it.

A thin, dusky (4/10) streak (Aethiops I ?) was visible projecting from the Northern/following border of Mare Cimmerium. Hesperia appeared shaded to bright (6-7/10) with dull (5/10) streaks across it. Mare Tyrrhenum appeared dark to dusky (3-4/10) and Syrtis Minor was dark (3/10). Zephyria, Aeolis, Aethiopis, and Aetheria appeared bright (7/10) without any other detail visible. Elysium appeared bright (7/10) on the CM with a dark to dusky (3-4/10) Phlegra to the east (preceding) and a dark to dusky (3-4/10) Hyblaeus Extension to the west (following).

Extremely bright (9/10) MLH, ELH, SPR, and NPR were noted.

Ironically the current diameter of Mars (15.6") is just smaller than the largest apparent diameter for the upcoming apparition (15.89" on December 18, 2007). The best of luck imaging and observing Mars.
