An automated system in detecting solar radio bursts type II and IV associated to multiple Coronal Mass Ejections

This paper presents an automated system named as CALLISTO which is implemented to record solar radio bursts emissions associated to solar activity. CALLISTO is a spectrometer used in solar activity observations in order to monitor the Sun's activity and behaviour and also as an indicator of upcoming solar events. Solar radio bursts type II is known as slow drift going from high to low frequency at a range of 20 MHz-150 MHz. It is found to be associated to Earth-directed Coronal Mass Ejections (CMEs) travelling at a very high speed. On 4th November 2015, type II and IV bursts were detected by Almaty and Bir station respectively along with multiple formation of CMEs throughout the day. Due to the shock wave from CMEs, a minor G1 storm was triggered on 7th November 2015 leaving an aurora scenery over the skies of several states in USA. However, no damages on power systems were reported. Comprehensive discussions on this event are discussed in this paper. (paper)
