You can help spot solar storms and comets online at solarstormwatch dot com. This is a site and application that lets you see images taken with NASA's STEREO satellites that are constantly watching the sun and the space around it.
It's kind of hard to describe but you basically watch videos of the sun and surrounding space and click on buttons to indicate what you see and then step back and forth through the video to locate just when you saw it..

STEREO (Solar TErrestrial RElations Observatory) is the third mission in NASA's Solar Terrestrial Probes program (STP). This two-year mission, launched October 2006, will provide a unique and revolutionary view of the Sun-Earth System. The two nearly identical observatories - one ahead of Earth in its orbit, the other trailing behind - will trace the flow of energy and matter from the Sun to Earth. They will reveal the 3D structure of coronal mass ejections; violent eruptions of matter from the sun that can disrupt satellites and power grids, and help us understand why they happen. STEREO will become a key addition to the fleet of space weather detection satellites by providing more accurate alerts for the arrival time of Earth-directed solar ejections with its unique side-viewing perspective.
