The Sun goes through regular cycles of activity approximately every 11 years, and tracking these cycles is a key part of better understanding the Sun and mitigating its impacts on human technology and astronauts in space.
Join scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA) for a special episode of NASA Science Live on Tuesday, Sept. 15, at 3 p.m. EDT as they discuss predictions for the upcoming solar cycle. The public can send questions during the event using #AskNASA on Twitter or by leaving a comment in the chat section on Facebook.
If you have the time and are available, this looks like it may be well worth it. I will even try to listen in the background from work.
