Space Weather News for March 30, 2009
MT. REDOUBT: Alaska's Mt. Redoubt volcano has erupted at least 19 times since March 22, and several of the most powerful blasts have spewed clouds of ash and sulfurous gas into the lower stratosphere.
The last time an Alaskan volcano blew its top (Kasatochi in August 2008), similar clouds caused fantastic sunsets around the Northern Hemisphere.
Today's edition of SpaceWeather News features satellite maps of Mt. Redoubt's sulfur dioxide emissions. Using these maps, we can track the volcanic clouds as they drift around the globe and be alert for unusual sunsets and other phenomena when they pass nearby.
