This hydrogen alpha image of the Sun that was captured today shows only a few small prominences. However, multiple sunspots (white due to the image being inverted to enhance detail) and filaments are visible. The largest of the sunspot groups (AR3226 in the upper left) was the site of a magnetic filament associated with a coronal mass ejection that is likely to hit the Earth.
