This work consists on analysis of evolution of an halo type coronal mass
ejection (CME) recorded on March 09, 2012 by LASCO instrument on board of SOHO
satellite. CME presented velocity of 950 m/s and the EUV images recorded by the
Extreme Ultraviolet Imager (EUVI), aboard the STEREO show evidence of shock wave
produced by the expansion of the CME. The event was also associated with an M.6
class X-ray solar flare, starting at 03:22 UT, peaking at 03:53 UT and ending at
04:18 UT, recorded by the GOES satellite. Also a type II radio bursts were recorded
in metric wavelength band (100-250 MHz) by e-Callisto spectrographs. The following
spectro-temporal parameters of type II burst were estimated from the dynamic
spectrum: starting frequency of (220 ? 5) MHz; ending frequency of (170 ? 5) MHz;
starting and ending time of about 03:41:51 UT and 03:46:49 UT; and frequency
bandwidth of 34,3 MHz. The results are presented and discussed. |
