Peculiarities of long-wave radio bursts from solar flares preceding strong geomagnetic storms
Yermolaev, Yu. I.; Kudela, K.; Prokudina, V. S. +2 more
Radio bursts in the frequency range of 100-1500 kHz, recorded in 1997-2000 on the INTERBALL-1 satellite during the solar flares preceding the strong geomagnetic storms with D st < -100 nT, are analyzed in this paper. The observed long-wave III-type radio bursts of solar origin at frequencies of 1460 and 780 kHz were characterized b…
Radial propagation velocity of energetic particle injections according to measurements onboard the Cluster satellites
Nakamura, R.; Sergeev, V. A.; Baumjohann, W. +4 more
Injections of energetic electrons with a dispersion over energies were observed during the February 23, 2004 (at about 03:20 UT) substorm onboard the Cluster satellites in the vicinity of perigee near the midnight meridian. The delays in the particle observation caused by the energy dependence of the magnetic drift velocities made it possible to d…
