First Simultaneous Observation of H-alpha Moreton Wave, EUV Wave, and Filament/Prominence Oscillations

Ayumi Asai, Takako T. Ishii, Hiroaki Isobe +9

We report on the first simultaneous observation of an H-alpha Moreton wave, the corresponding EUV fast coronal waves, and a slow and bright EUV wave (typical EIT wave). Associated…

A Study on Red Asymmetry of H-alpha Flare Ribbons Using Narrowband Filtergram in the 2001 April 10 Solar Flare

Ayumi Asai, Kiyoshi Ichimoto, Reizaburo Kitai +2

We report a detailed examination of the "red asymmetry" of H-alpha emission line seen during the 2001 April 10 solar flare by using a narrowband filtergram. We investigated the tem…

Simultaneous Observation of Reconnection Inflow and Outflow Associated with the 2010 August 18 Solar Flare

Shinsuke Takasao, Ayumi Asai, Hiroaki Isobe +1

We report the simultaneous extreme ultraviolet observation of magnetic reconnection inflow and outflow in a flare on 2010 August 18 observed by the Atmospheric Imaging Assembly on…

Center-to-Limb Variation of Radio Emissions from Thermal-Rich and Thermal-Poor Solar Flares

Tomoko Kawate, Ayumi Asai, Ichimoto Kiyoshi

A statistical analysis of radio flare events was performed by using the event list of Nobeyama Radioheliograph in 1996-2009. We examined center-to-limb variations of 17GHz and 34GH…

Numerical Investigation of a Coronal Mass Ejection from an Anemone Active Region: Reconnection and Deflection of the 2005 August 22 Eruption

N. Lugaz, C. Downs, K. Shibata +3

We present a numerical investigation of the coronal evolution of a coronal mass ejection (CME) on 2005 August 22 using a 3-D thermodynamics magnetohydrodynamic model, the SWMF. The…
