Solar explosions seen

Now that the Sun has become more active again, lots more prominences and Coronal Mass Ejections are being seen (not least the ones that keep smacking into us).

On the 3rd of April, the STEREO spacecraft captured this movie of an eruption.

Meanwhile, today SoHO captured this image of a series of events summarised in this movie.

Of course, you don’t need a satellite to see something like this – a good filter or a solar telescope will do the job nicely, as proven in this image by Richard Bailey, director of the solar observing section in the Society for Popular Astronomy.
