Abstract
The initiation of the Coronal Mass Ejection (CME) on 30 December 2004 at 10:57 UT, with an initial speed of 1250 km/s, has been studied using multiwavelength data. EUV and radio H-alpha images play a significant role in identifying multiple reconnections. The reconnection occurring in the northern and southern parts of Active Region (AR10715) led to C1.3 and M2.2 flares. The southern arcade system expands and reconnects with the overlying field lines, resulting in a fast, wide CME. Hence, our multiwavelength analysis provides evidence that internal reconnection, followed by external reconnection, causes large-scale eruption at 10:50 UT. Radio signatures also support this scenario.
期刊介绍：
Astrophysics and Space Science publishes original contributions and invited reviews covering the entire range of astronomy, astrophysics, astrophysical cosmology, planetary and space science and the astrophysical aspects of astrobiology. This includes both observational and theoretical research, the techniques of astronomical instrumentation and data analysis and astronomical space instrumentation. We particularly welcome papers in the general fields of high-energy astrophysics, astrophysical and astrochemical studies of the interstellar medium including star formation, planetary astrophysics, the formation and evolution of galaxies and the evolution of large scale structure in the Universe. Papers in mathematical physics or in general relativity which do not establish clear astrophysical applications will no longer be considered.
The journal also publishes topically selected special issues in research fields of particular scientific interest. These consist of both invited reviews and original research papers. Conference proceedings will not be considered. All papers published in the journal are subject to thorough and strict peer-reviewing.
Astrophysics and Space Science features short publication times after acceptance and colour printing free of charge.
