Coronal Mass Ejections (CMEs) are well known as one of the most massive eruptions which potentially create major disturbances in theinterplanetary medium and initiate severe magnetic storms when they collide with the Earth's magnetosphere. As indicated with radio signatures so-called type II and III burst. It also divided by sub-type of burst depending on the physical characteristics and different...

Halo event of coronal mass ejections (CMEs) had been once in a while reported in coronagraph observations of the Sun before the Solar and Heliospheric Observatory (SOHO) mission has been carried out. However, since mid-1996 the SOHO Large Angle Spectrometric Coronagraph (LASCO) instruments have observed numerous halo or partial-halo CMEs. Partial halo is when CMEs aimed at Earth which is called as...

Solar radio burst originated at the layer of the atmosphere where the Geo-effective disturbance occurred which energy will be released in solar flares and Coronal Mass Ejections (CMEs) will be launched. Solar Radio Burst can be divided into 5 types and determined by using the Log Periodic Dipole Antenna (LPDA) and e-CALLISTO system. The LPDA was set up in a 45-870 MHz range in frequency and has maximum...

The solar radio bursts are the results of solar flares take place on the surface of the Sun. Some of them could reach the surface of the Earth and can be detected by the ground base antenna. The CALLISTO system is used to interpret the radio bursts that have been detected by the antenna before the results appeared on the computer's screen. The CALLISTO system consists of software and hardware with...

Managing a project involves a process of synchronizing two different organizations with two different cultures. In doing so, mutual agreement on certain things and levels is a must for that project to be run smoothly. Therefore, the objective of this paper is to identify the essential requirement for school-university collaboration specifically for 'Creating Awareness on Light Pollution' (CALP) Project...

The Callisto network systems are widely used for continuous data collection of solar activities every day through the internet connection and stored in the central database in the computer. The system installation began in 2002 in Zurich, and its network has spread all around the globe ever since, benefiting researchers and individuals worldwide. This research paper presents one of selected event...

Abstract- This paper highlighted on the unique occurrence of the Solar Radio Burst Type III (SRBT III) during the high activities of the Sun. e- CALLISTO network is the system that responsible for the observation of the Sun 24 hours per day, which is a program under IHY/UNBSSI and ISWI instrument deployment program. The data was taken from one of the part of e-CALLISTO network which is Bleien, Switzerland...

Light pollution is an anthropogenic by-product of modern civilization and heavy economical activity, sourced from artificial light. In addition of its detrimental impact on human, and ecology, light pollution brightens the night sky, limiting the range of visible astronomical bodies detected by naked-eye. Since it is becoming a global concern for astronomers, the level of light pollution needs to...

The E-CALLISTO (Compact Astronomical Low Cost Frequency Instrument for Spectroscopy and Transportable Observatory) network is a worldwide system in order to observe the Sun's activity in the radio region. At present, more than 80 instruments have been installed at more than 43 locations, with users from more than 113 countries in the e- CALLISTO network. At present, more than 80 instruments have been...

Solar radio burst becoming an interesting topic among solar physicists in order to study the Space Weather condition. It generally originate at the same level as solar flare, Coronal Mass Ejection (CME) and shock at solar atmosphere which the Sun project the radio energy into the interstellar medium. In this study, the relation between solar radio burst type II, III and IV due to active region AR2157...

Type I solar burst were identified based on data recorded by CALLISTO BLEIN, Switzerland in the period of 17th of January, 2011. Solar Radio Burst Type I is one of the main type of solar burst which is believed to provide a diagnostic of electron acceleration in the corona. This noise storm burst is associated with emerging and growing active regions and last from hours to days. It can be observed...

The formation of detected solar radio burst type II occurred was captured using Compound Astronomical Low Cost Frequency Spectrometer Transportable Observatory (CALLISTO) system which gives a better resolution of a wonderful image than other countries. The phenomenon was found on 2nd November 2014 at 09:39 [UT] in Switzerland. CALLISTO spectrometer device detects and traces a Coronal Mass Ejections...

Recent data of a complex solar radio burst type II is analyzed and reviewed. The monitoring of solar radio burst was done by using the Compact Astronomical Low cost, Low frequency Instrument for Spectroscopy and Transportable Observatory (CALLISTO) from BLEIN 7 meter dish telescope at ETH, Zurich in frequency range of 25 until 1000 MHz. During the inspection of the X-ray spectrum, we observed that...

This event allows us to investigate how plasma–magnetic field interactions in the solar corona can produce suprathermal electron populations over periods from tens of minutes to several hours, and the interactions of wave-particle and wave-wave lead to characteristic fine structures of the emission. An intense and broad solar radio burst type IV was recorded by CALLISTO spectrometer from 240360 MHz...

A preliminary correlation study of the herring − bone type II with a type III solar burst of has been made. On the basis of this study and in combination with the observation in radio emission, an interpretation of the mechanism of the occurrence of this event has been proposed. The type II solar radio burst with a split and herring bone is occurring at the same time from 36 MHz till 50 MHz. We have...

The present article is an attempt to analyze the solar burst Type II observations based on solar flare and Coronal Mass Ejections (CMEs) events. We choose an intriguing type II radio burst with a velocity of 1193 kms-1 that occurred on 2012 November 13 at 2:04:20 UT. In this case, the study of solar radio burst type III is of paramount importance because of the fact that it helps to gain an insight...

A compact solar flare was observed during a total solar eclipse event on 13-14 November 2012. This phenomenon is beginning in local time on November 14 west of the date line over northern Australia, and ended in local time on November 13 east of the date line near the west coast of South America. During the eclipse, the highest magnitude was 1.0500, occurring only 12 hours before perigee, with the...
