Hello Everybody, I attach a detail from the STEREO WAVES spectrum: http://swaves.gsfc.nasa.gov/data/s-waves-ds/2010/swaves_summary_20100818_c.png The black time ticks are at 6 and 7 UT. The white line is at 16 MHz, and the upper edge is near 2 MHz (log scale). This was an interesting flare and radio event. The flare and CME look beautiful, just below the western limb, in the movie: http://sdowww.lmsal.com/sdomedia/ssw/ssw_client/data/ssw_service_100818_032522_31724449/www/ssw_cutout_20100818_043001_aia_171_N17W88_20100818_043000_m.mpg The type III activity lasted for about 30 minutes at 16 MHz, and it was followed by type II. I think we see fundamental and second harmonic, but I have not checked carefully the frequencies. The overall event, down to low frequencies, lasted more than 4 hours. As you know, the type II drift rate is much slower than type III. Victor //www.freelists.org/archive/radioastro
