Occurrence Rate of Radio-Loud and Halo CMEs in Solar Cycle 25: Prediction Using their Correlation with the Sunspot Number

The coronal mass ejections (CMEs) from the Sun are known for their space weather and geomagnetic consequences. Among all CMEs, so-called radio-loud (RL) halo CMEs considered most energetic in sense that they usually faster wider than general population of CMEs. Hence study RL has become important prediction occurrence rate a future cycle will give warning advance. In present paper, rates solar (SC) 25 predicted. For this, we obtained good correlations between numbers each year yearly mean sunspot previous two cycles. predicted values SC by NOAA/NASA were as representative indices corresponding have been determined using linear relations. Our results show maximum number be around 39 $/pm$ 3 45 4, respectively. Removing backside events, set front-side events was also separately alone again. peak estimated to 31 29 These discussed comparison with sunspots different authors.
