Session Description | Flare activity is one of the most prominent eruptive phenomena observed in the solar atmosphere. Radiation form flaring, such as EUV and X-ray emissions, can affect the upper atmosphere and ionosphere of the Earth promptly within several minutes. The solar energetic particles (SEPs) and coronal mass ejections (CMEs) associated with flares can affect the space weather conditions of the Earth within tens of minutes or days. Since the sighting of the devastating solar flare on 1 September 1859, also known as the Carrington flare, via white light wave band, the observation techniques and approaches for the Sun have achieved great advances. Nowadays, the detailed evolution of even the local solar atmosphere before, during, and after a flare can be observed by ground- and space-based facilities in high spatial, temporal, and spectral resolution. The new observational data by the latest space satellites, such as RHESSI, Hinode, STEREO, SDO and IRIS, as well as the newly constructed ground-based solar telescopes greatly promote the physical understandings of the flare mechanism. The routine monitoring of the Sun by satellites and the ground-based solar observing station networks also greatly improves the solar flare forecasting capability. In this session, it is aimed to facilitate a series of topical discussions on all aspects of flare activity, which include but are not limited to the analyses of the direct observations and the underlying physical mechanisms, MHD modeling, as well as prediction methods and operational forecasting. Discussions on comparative analyses between solar and stellar flares are also anticipated. |
