Planet Venus
Sketch and Details by Carlos E. Hernandez
I made an observation of Venus on February 10, 2009 (00:30 U.T.) using my 9-inch (23-cm) F/13.5 Maksutov-Cassegrain (248x) under average to good seeing conditions (5-7/10). The central meridian was 271.7 degrees West, phase 35% (p 0.350), and apparent magnitude of -4.6. I was using a magenta (Wratten 30) filter, enhances both red and blue features and darkens green ones, to bring out the subtle albedo features over the Venusian cloud tops. I was able to make out delicate albedo features over the visible globe and especially along the terminator. Obviously they became more apparent when the seeing steadied for brief moments.

Carlos,
Very interesting sketch!
I saw some clouds like structures month ago. I still wonder if this are clouds or no. Are You sure, You noticed Venus clouds?
What do You think, guys?

Carlos,
Very impressive sketch of the Venusian albedo features. I also like that magenta filter for seeing the cloud details especially near the terminator. Always a pleasure to see your sketches here.
