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…
Statistical Study on the Nature of Solar Flux Emergence
Kenichi Otsuji, Reizaburo Kitai, Kiyoshi Ichimoto +1
We studied 101 flux emergence events ranging from small ephemeral regions to large emerging flux regions which were observed with Hinode Solar Optical Telescope filtergram. We inve…
Ellerman Bombs at high resolution: I. Morphological evidence for photospheric reconnection
Hiroko Watanabe, Gregal Vissers, Reizaburo Kitai +2
High-resolution imaging-spectroscopy movies of solar active region NOAA 10998 obtained with the CRisp Imaging SpectroPolarimeter (CRISP) at the Swedish 1-m Solar Telescope show ver…
