eruptions which potentially create major disturbances in the interplanetary medium and initiate severe
magnetic storms when they collide with the Earth‟s magnetosphere. However, how far the solar flare
can contribute to the formation of the CMEs is still not easy to be understood. These phenomena are
associated with II and III burst it also divided by sub-type of burst depending on the physical
characteristics and different mechanisms. In this work, we used a Compound Astronomical Low-cost
Low-frequency Instrument for Spectroscopy in Transportable Observatories (CALLISTO) system.
The aim of the present study is to reveal dynamical properties of solar burst type II and III due to
several mechanisms. Most of the cases of both solar radio bursts can be found in the range less that
400 MHz. Based on solar flare monitoring within 24 hours, the CMEs that has the potential to explode
will dominantly be a class of M1 solar flare. Overall, the tendencies of SRBT III burst form the solar
radio burst type III at 187 MHz to 449 MHz. Based on solar observations, it is evident that the
explosive, short time-scale energy release during flares and the long term, gradual energy release
expressed by CMEs can be reasonably understood only if both processes are taken as common and
probably not independent signatures of a destabilization of pre-existing coronal magnetic field
structures. The configurations of several active regions can be sourced regions of CMEs formation.
The study of the formation, acceleration and propagation of CMEs requires advanced and powerful
observational tools in different spectral ranges as many „stages‟ as possible between the photosphere
of the Sun and magnetosphere of the Sun and magnetosphere of the Earth. In conclusion, this range is
a current regime of solar radio bursts during CMEs events.

Every occurrence in the Sun gives significant impact towards us. In this research we try to obtain Wolf number, class of sunspots and measuring rotation period. As Wolf number is index to Sun’s activity. Sun’s activity indicate climate changes on Earth and space weather.

These bursts occurred on 9th March 2012 at the National Space Centre, Sg. Lang, Selangor, Malaysia Here, we study a unique case with a combination of two types burst associated with solar flare and CMEs. Our observation is focused on the low frequency region starting from 150 MHz till 400 MHz. We found that a solar flare type solar flare type M 6.3 which occurred in active region AR 1429 starting from 3:32 UT and ending at 05:00 UT. The flare has been confirmed to be the largest flare since 2005. Some physical parameters will be measured. We then compared our results with X-ray data from NOAA Space Weather Prediction Centre (SWPC)
