The Power-Law Distribution of Flare Kernels and Fractal Current Sheets in a Solar Flare
N. Nishizuka, A. Asai, H. Takasaki +2
We report a detailed examination of the fine structure inside flare ribbons and the temporal evolution of this fine structure during the X2.5 solar flare that occurred on 2004 Nove…
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…
The X10 Flare on 2003 October 29: Triggered by Magnetic Reconnection between Counter-Helical Fluxes?
Y. Liu
Vector magnetograms taken at Huairou Solar Observing Station (HSOS) and Mees Solar Observatory (MSO) reveal that the super active region (AR) NOAA 10486 was a complex region contai…
Difference between Spatial Distributions of the H-alpha Kernels and Hard X-Ray Sources in a Solar Flare
Ayumi Asai, Satoshi Masuda, Takaaki Yokoyama +4
We present the relation of the spatial distribution of H-alpha kernels with the distribution of hard X-ray (HXR) sources seen during the 2001 April 10 solar flare. This flare was o…
Plasma Ejections from a Light Bridge in a Sunspot Umbra
Ayumi Asai, Takako T. Ishii, Hiroki Kurokawa
We present conspicuous activities of plasma ejections along a light bridge of a stable and mature sunspot in NOAA 8971 on 2000 May 02. We found the ejections both in the H-alpha (1…
Emergence of a Twisted Magnetic Flux Bundle as a Source of Strong Flare Activity
Takako T. Ishii, Hiroki Kurokawa, Tsutomu T. Takeuchi
Sunspot proper motions and flares of a super active region NOAA 5395, which was the biggest and the most flare-active region in the 22nd sunspot cycle, were analyzed in details. We…
