The rapidly evolving Active Region AR1504 has been producing several C-class solar flares and even three stronger M-class solar flares. As this active region rotates towards Earth we keep our eye on this region, as well as AR1505, 1506 and 1507.

The video starts off with a view from June 9 to 12 in the 171 angstrom wavelengths and it shows us the many coronal loops extending off of the Sun where plasma moves along magnetic field lines.

Then we switch to the 304 angstrom view, seeing the M-class solar flares.
