Abstract : The coronal mass ejections (CMEs) from the Sun are known for their space weather and geomagnetic consequences. Among all CMEs, the shock associated CME (radio-loud CME: RL CME) and halo CMEs are considered the most energetic and they are important to predict. In the paper, the occurrence rates of RL and halo CMEs in solar cycle (SC) 25 are predicted. We found that good positive correlations between the numbers of RL and halo CMEs in each year and the yearly mean sunspot numbers (SSN) for the SC 23 and SC 24. The predicted values of sunspot numbers in SC 25 by NOAA/NASA were considered as representative indices and the corresponding numbers of RL and halo CMEs have been determined using linear relations. Our results show that the maximum number of RL and halo CMEs will be around 39 ± 3 and 44 ± 4, respectively. The peak values of front-side RL and halo events have been estimated to be around 31 ± 3 and 29 ± 3 respectively.
