NASA Science Update to Discuss Anatomy of Solar Storms

WASHINGTON -- NASA will hold a Science Update at 1 p.m. EDT, Tuesday, April 14, to present new findings and three-dimensional views revealing the inner workings of solar storms known as coronal mass ejections. The data will improve the ability to predict how and when these solar tsunamis impact Earth, affecting communication systems, power grids, and other technology. The briefing will take place in the James E. Webb Memorial Auditorium at NASA Headquarters, 300 E St., S.W., and will be carried live on NASA Television.

Reporters may ask questions from participating NASA locations or listen and ask questions by phone. For dial-in information, journalists should send an e-mail to j.d.harrington@nasa.gov listing name, media affiliation, and telephone number. Briefing visuals are listed below.
