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.

Briefing participants are:

-- Michael Kaiser, project scientist, Solar Terrestrial Relations Observatory (STEREO), NASA's Goddard Space Flight Center in Greenbelt, Md.
-- Angelos Vourlidas, project scientist, Sun Earth Connection Coronal and Heliospheric Investigation, Naval Research Laboratory in Washington
-- Antoinette Galvin, principal investigator, Plasma and Suprathermal Ion Composition instrument, University of New Hampshire in Durham
-- Madhulika Guhathakurta, STEREO program scientist, NASA Headquarters

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.
