Seminar Abstract:

NASA’s Solar Dynamics Observatory has returned over 60 million images of the Sun in its first 22 months of taking data. This data has given us spectacular views of flares and erupting prominences. We have learned how to predict when magnetic field will emerge from the surface and why satellite drag caused by solar flares is more complicated then we thought. A comet flew across the face of the Sun on July 6, 2011, causing a bright tail in the images. We are still asking why it was bright. Come hear about the images, see some movies, and learn about the new results from SDO.
