Photometric Analysis of CME in the rising phase of solar cycle 24

Abstract

As world become more technologically advanced it become more important to study and forecast solar events which materialize by solar activity, the Sun goes through solar activity cycle, where every 11 year. In this investigation the highest position in the rising phase of solar cycle 24 had been studied by analyzing the photometric observations of coronal mass ejection (CME) for the year 2013 for the months 2,3,4,5that were derived from Large Angle and Spectrometric Coronagraph Experiment (LASCO), which is one of the scientific systems in the spacecraft Solar and Heliospheric Observatory (SOHO), that was located close Lagrangian point L1. From all previous observations and from the intensity time profile of it, the onset time had been calculated and from it the injection time of CMEhad been measured in order to find the lift of time and the associated flares. And also from the intensity-time profile any clear raising from background give indication for solar event, thus, the roots of the eruption in the sun will be determined.It had been concluded that The important event for this year in March and May also the acceleration of the energetic particle not only in the interplanetary, but also in the location of the event in the corona of the Sun, and it had been found that the event increased gradually with adopted months (2,3, 4, 5). Also it has been noticed that most of solar events have multi eruption phenomena.
