Multi-wavelength study of a flare and burst associated coronal mass ejection
The present study consists of the radio emissions observed on 15 May 2013 by ground based and space based radio observations. An intensive solar X-ray flare from the location N12E64 was associated with a halo coronal mass ejection (CME) of speed 1366 km/s observed in white light by Solar and Heliospheric Observatory (SOHO)/Large Angle Spectrometric Coronagraph (LASCO) coronagraph. Metric type II and IV radio emission were detected by Culgoora and Bruny island radio spectrograph (BIRS) after flare onset. Also, decameter-hectometric (DH) type II radio burst was detected by wind/radio and plasma wave experiment (WAVES). The low frequency radio signature was found to be generated between 8-42 Ro (Ro = one solar radius). From the analysis, both the high and low frequency type II radio signatures seem to be generated due to shock driven by the CME. This CME was also associated with SEP, IP shock and geomagnetic storm.
