Another Mars Pic
Another image of Mars taken May 17. Note the phase and Syrtis Major, the large triangular formation. Given the rather poor seeing last night and the small (9 arcsecond) diameter of the planet, a surprising amount of detail is visible. Around the 1 o'clock position, the smaller, northern polar cap can be seen. The lightening of the area south of Syrtis Major (at the 7 o'clock position), indicates the position of the larger, southern polar cap.
