For almost a week, dust has been sweeping over the Red Sea (center) from East Africa. This Moderate Resolution Imaging Spectroradiometer (MODIS) from the Aqua satellite shows the region on June 25, 2003. A thick dust plume (tan pixels) is stretching out from the Sudan coastline (left) and has almost reached Saudi Arabia (right). The entire scene is thinly veiled with a layer of dust, giving the image a soft appearance.
