要約

Analyzed are the properties of powerful (fluxes greater than 10−19 W (m2·Hz)) type III bursts been observed in July−August 2002 with the UTR-2 radio telescope at frequencies 10−30 MHz. The majority of these bursts have been recorded on the days when the active region was located near the central meridian, or 40 to 60 deg. eastwards or westwards from it. All the bursts were drifting from high to low frequencies, their drift rates lying in most cases within 1−2.5 MHz/s. During all observational days, the frequency drift rate has linearly grown with frequency. The duration of powerful type III bursts vary in general from 6 to 12 s, with smaller values for higher frequencies. The instantaneous frequency bandwidth of these bursts does not practically depend on the day of observation and shows a linear growth with frequency. The observational data are interpreted within the standard plasma model for the type III burst generation.
