Statistical Analysis of Decimetric Radio Bursts, Flares, and Coronal Mass Ejections

A statistical analysis of decimetric radio bursts (RBs), X-ray flares and coronal mass ejections (CMEs) is carried out. We consider all radio bursts recorded by the Cracow Solar Radio Telescope from the beginning of 1996 until the end of 2004. It is found that the decimetric radio bursts are associa...

Description
Summary:A statistical analysis of decimetric radio bursts (RBs), X-ray flares and coronal mass ejections (CMEs) is carried out. We consider all radio bursts recorded by the Cracow Solar Radio Telescope from the beginning of 1996 until the end of 2004. It is found that the decimetric radio bursts are associated and strongly correlated with X-ray flares. Correlation coefficients between RBs durations and the maximal fluxes of the radio bursts and flares are found to be 0.60 and 0.87, respectively. We also demonstrated that a significant population of the decimetric radio bursts are associated with CMEs. The correlation coefficient between the maximal radio flux density multiplied by the duration of the RBs versus velocity multiplied by width of CMEs is found to be 0.55.
