Solar Shield at Goddard's Community Coordinated Modeling Center for power
transformer level predictions
Hello Radio Astronomers,
This interesting NASA Science News article:
http://science.nasa.gov/science-news/science-at-nasa/2010/26oct_solarshield/
discusses the tremendous power of large Coronal Mass Ejections. They can
induce huge currents in the electric power system, damage transformers, and
cause blackouts lasting for hours.
I quote:
"The innovation of Solar Shield is its ability to deliver transformer-level
predictions. Pulkkinen explains how it works:
"Solar Shield springs into action when we see a coronal mass ejection (CME)
billowing away from the sun. Images from SOHO and NASA's twin STEREO
spacecraft show us the cloud from as many as three points of view, allowing
us to make a 3D model of the CME, and predict when it will arrive ....
We work at Goddard's Community Coordinated Modeling Center (CCMC)," says
Pulkkinen. The CCMC is a place where leading researchers from around the
world have gathered their best physics-based computer programs for modeling
space weather events. The crucial moment comes about 30 minutes before
impact when the cloud sweeps past ACE, a spacecraft stationed 1.5 million km
upstream from Earth. Sensors onboard ACE make in situ measurements of the
CME's speed, density, and magnetic field. These data are transmitted to
Earth and the waiting Solar Shield team. "
