The earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13665 dust plume that blew off the coast of Sudan on June 21, 2006, had petered out a day later. The Moderate Resolution Imaging Spectroradiometer modis.gsfc.nasa.gov/ (MODIS) flying onboard NASA's aqua.nasa.gov/ Aqua satellite took this picture on June 22. In this image, the dust plume has dissipated and heads southward over the Red Sea toward the coasts of Eritrea and Yemen. Largely opaque the day before, the dust plume is now thin enough to show the ocean's surface.
