AR 12192, the most prolific of Solar Cycle 24, rotated into view on 18 Oct 2014 but announced its presence on 14 Oct 2014 with a powerful and unusual eruption. Producing the largest post-eruptive loop system of the solar cycle.. Abstract. We observed a filament eruption, whose shape is like a dandelion, associated with the solar flare that occurred on 2011 February 16 at the active region NOAA 11158.
