Cristiani2 Abstract Type : Poster Abstract Category : Sun, Solar System, Exoplanets, and Astrobiology Abstract : Solar filaments are cool and dense plasma material suspended in the solar corona against gravity. Their eruptions are crucial from the space weather point-of-view. Here, we present observations of a quiescent filament eruption that occurred on 13 July 2015. The eruption was associated with a clear two-ribbon GOES B7 class flare. The successful eruption produced a CME with a speed of ~ 552 km s-1 and a deceleration of ~ 14 m s-2. To understand the origin of the filament eruption, we have computed the magnetic flux at different locations near the filament and conclude that magnetic flux cancellation could be the cause of this eruption. During the eruption, the nearby EUV loops contract, which is explained in light of existing theories and simulations. |
