Sketching at the telescope: Stephen O’Meara’s Mars

on Friday, May 21, 2010

The Mare Sirenum-Mare Cimmerium region of Mars sketched by Stephen James O’Meara with the 60-inch telescope at Mount Wilson, California. The dark albedo feature near the center is what O’Meara termed “Valhalla.” This observation was made August 7 of an unknown year. David J. Eicher library

This sketch by Contributing Editor Stephen James O’Meara is of the “Valhalla” region on Mars, which was famously first observed by Steve in 1988. The drawing is undated except for “August 7, 7–11 hours U.T.” and shows the dark albedo feature known as Valhalla in the center of the frame, running parallel to Mare Sirenum and Mare Cimmerium. Steve made this drawing with the 60-inch telescope at Mount Wilson Observatory outside Los Angeles.
