| contents | Statistical analysis of dynamical parameters of solar ejections observed from 1996 to 2006 Guadalupe Muñoz Bernardo Vargas José Luis López-López Ciencias de la Tierra solar wind statistics dynamical parameters coronal mass ejections In this work we show a statistical analysis of the main parameters ofsolar ejections observedfrom January 1996 to December 2006 and reported on the SoHO-LASCO CME Catalog by the Coordinated Data Analysis Workshops (CDAW); this catalog contains the most complete data bank of coronal mass ejections (CMEs) ever compiled. The parameters of the CMEs analyzed are: angular position, angular width, speed and acceleration. For them, we obtained the distribution for each parameter and their representative values in order to characterize CMEs during solar cycle 23. These values are compared with the ones reported by previous analyses; we found that extreme values (maximum and minimum) are, for this sample, even more extremes. We discuss some specific cases from where can be shown that such extreme values correspond not only to a higher sensibility of the instruments, but to an overestimation of the values, and the consideration of events that are not properly CMEs. 2010 artículo científico 1026-8774 https://www.redalyc.org/articulo.oa?id=57216002015 en http://www.redalyc.org/revista.oa?id=572 Revista Mexicana de Ciencias Geológicas application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Ciencias Geológicas (México) Num.2 Vol.27 |
