Multi-wavelength investigation of energyrelease and transportin the 16 August 2004 flare

摘要

The current contribution investigates the solar flare of 16th August 2004 with themulti-wavelength observations with high temporal resolution from RHESSI, Large Solar Vac-uum Telescope (LSVT), Hiraiso Solar observatory, Nobeyama Radioheliograph (NoRH, 17 and34 GHz) and Siberian Solar Radio Telescope (SSRT, 5.7 GHz), TRACE. The main flare waspreceded by a pre-flare event with a very short energy release time. The observations of themain flare reveal a close temporal correlation between the Ha intensity observed with LSVTand those in hard and soft X-ray emissions observed with RHESSI, and in microwave fluxesobserved with NoRH and SSRT. This close temporal correlation can be only associated withhigh-energy particles. The role of energetic particles in energy transport and non-thermal ex-citation and ionisation on Hα emission during the pre-flare and pre-flare event is investigatedwith full non-LTE approach and possible agents and scenarios of energy transport are discussed
