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.
Highlights
The Sun goes through what it call a solar activity cycle, where every 11 year it will go from a very low period of solar activity, meaning a Sun spot and solar wind to another period of law activity and in between it goes through what it call solar maximum
Coronal Mass Ejections (CMEs) have been observed since the 1970s but in the last 15 years they have moved to the forefront of coronal research as evidenced by hundreds of publications [1]
In particular photometric observation had been analyzed for the rising phase of solar cycle 24 especially the year 2013 by using the photometric scale observation from Large Angle and Spectroscopic Coronagraph (LASCO) in order to find speed of the coronals, its width, acceleration and the central position angle (CPA), the intensity- time profile, energy and the shape of events obtained from energetic and relativistic nuclei electrons detector ERNE
