The Sun is approaching a minimum of solar activity, but this does not mean everything is calm in space. On March 22nd, 2019, IRIS observed an active region that had quickly appeared earlier and had many solar flares. In this video we can see many flares exploding over and over. Repeated eruptions take place over several hours, releasing large amounts of energy and particles into space.
