| Abstract: | The solar flare of 16th August 2004 was preceded by a very short energy release pre-flare event. The observations reveal a close temporal correlation between the H$\alpha$ intensity observed with LSVT, hard and soft X-ray emissions observed with RHESSI, and microwave fluxes observed with the Nobeyama Radioheliograph (NoRH) and the Siberian Solar Radio Telescope (SSRT) that can be caused only by high-energy particles. However, the most active kernel did not demonstrate significant linear polarization and HXR sources. How did energy transfer to this location and what is the reason for the absence of polarization? This current contribution will try to answer these questions employing the observations with high temporal resolution from RHESSI, Large Solar Vacuum Telescope (LSVT), Hiraiso Solar observatory, NoRH (17 and 34 GHz) and SSRT (5.7 GHz). Possible scenarios of energy transport in this flare are discussed. |
