Fig. 1.  SOHO/EIT (a) and LASCO/C2 (b) images show the region of the eruptive flare event of 14 July 2000 and related halo CME. The compressed inverted IZMIRAN dynamic radio spectrum in 05:50-13:00 UT interval (c) and extracted time-intensity profiles (d) at 58 MHz (right axis) and 86 MHz (left axis) display large-scale restructuring of the noise storm associated with the event: sharp weakening of the pre-existing noise storm in the 75-100 MHz range and some intensification of  radio emission at lower frequencies. The horizontal stripes are interferences from TV and radio stations.
