STEREO: 360° of Sun • Intro to STEREO • STEREO Science – some hits from the last few years • STEREO – All around the Sun • What’s happening • Why its important • Resources
SDO STEREO NASA/GSFC s3_heliocentricFeb2011_6fps.mov
STEREO Science Objectives • Understand the causes and physics of Coronal Mass Ejections (CMEs) • Track how CMEs move through space • Discover the sources of dangerous solar energetic particles (SEPs) • Map the 3D structure of the solar wind STEREO-A/SECCHI s4_prom_20100831a_cor2.mpg
Space Weather Effects • Satellite Damage and Difficulties • Dangers to Astronauts • Communications Black Outs and Radio Difficulties • GPS Errors • Problems with Air Travel Near the Poles • Flow of Currents on Pipelines • Electric Power System Problems • Confused Homing Pigeons
STEREO Imagers (SECCHI) EUVI – Extreme Ultraviolet images Cor1 and Cor2 – Coronagraphs Heliospheric Imagers (HI), imaging the rest of the way from the Sun to Earth orbit

Sun 360 • Media Events • Press conference: Feb. 9 at 2:00 PM US Eastern Standard Time http://www.nasa.gov/multimedia/nasatv/index.html?param=public • Twitter session for the public: Feb. 10, 1:30 -2:30 EST hashtag #sun360 Resources • Press conference movies • Handout (STEREO_allSun.pdf) • 3D projection: Working with Science on a Sphere (SOS). 10 min cadence movies showing 195 and 304 Å. Please register any events with the Museum Alliance
STEREO on a Smart Phone “3D Sun” on iPhone “Solaris” on Android
What would people use/like? • Flat screen movies showing rotating sun at particular time. • Produce after press conference? • Wavebands? • Number of frames in revolution? • Movie Format (frames, mpg, etc.)? • Projected Maps – good for wrapping over spheres. • SOS uses series of these to make movies. • Smart phone apps use individual ones for their zoom & pan displays • Anyone else want these?
