Super-Typhoon Choi-wan had a symmetrical shape, a trait of a strong, well-organized cyclone, when this photo-like image was taken on September 16, 2009.
Though Typhoon Choi-wan maintains its tightly wound symmetric shape in this photo-like image from September 18, 2009, the striking clear eye of previous days is gone.
Acquired October 1, 2009, this true-color image shows Typhoon Parma headed westward over the Pacific Ocean. Outlined in black in the left half of the image are parts of the Philippines.
