HELIOPHYSICS PICTURE OF THE WEEK


"Sunspot Closeup"

On December 13, 2006, Hinode caught sunspot 930 in the act of erupting. There was an X3-class solar flare, a billion-ton coronal mass ejection, and spectacular auroras on Earth. Now, with a high-resolution movie to study, astronomers can see what caused the explosion: Two sunspots of opposite magnetic polarity, too close together. Boom!

You can see a movie of this on spaceweather.com.

IHY OBSERVATORY OF THE WEEK


HINODE

This exciting new spacecraft is named for the word "Sunrise" in Japanese. Launched last fall, Hinode has indeed shined upon us, bringing us a wealth of new information about the Sun's magnetic structure and the flares and eruptions that result. Built by the Japanese Aerospace Exploration Agency (JAXA) in cooperation with the US and UK, the new data is generating interest all around the world.

IHY ACTIVITY OF THE WEEK


Cooking With the Sun

There are many ways to use solar power, on Earth and in space. Most of the participating IHY spacecraft have solar panels to supply energy for multi-year missions. Some missions are even planning to use Solar Sails as a source of propulsion. You can even make a solar pizza.
