This is an awesome image of the Sun captured by Efrain Morales Rivera from the Jaicoa Observatory in Aguadilla, Puerto Rico, on December 31, 2011. It shows multiple steam-like prominences on the eastern limb of the Sun. Rivera compared them to a group of trees, and said the now-active Sun is definitely something to watch in the coming new year. Of course, the Solar Dynamics Observatory is keeping a close watch on our star, and captured a huge eruption on the western limb of the Sun on January 2, 2012, with lots of solar material ejected into space; however, it was not Earth-directed.

    Does anyone know how the current action of solar cycle 24 compares to the same time period in solar cycle 23 or previous cycles?
