"S" Marks The Spot For Solar Activity
News story originally written on March 10, 1999
Scientists have observed a structure on the sun that might help them
forecast coronal mass ejections
. CME's can
cause problems with communications and damage satellites. They can also
disrupt electrical power grids.
An S-shaped pattern was found to appear a few days before a CME. The
pattern is most likely caused by twists in the solar magnetic field
Scientists believe that CME's get their energy from the magnetic field on
