摘　　要：The solar radio inverted-U bursts are named after their shape of an inverted letter Uon the spectrograph records.They are important in the study of the corona mass ejectionand particle acceleration in solar flares.Up to now,most U bursts occur at frequenciesbelow 0.5 GHz;only one exception was reported in the 1.1—1.7 GHz frequency band.Inthis note,we investigate a U burst in the 1.0-2.8 GHz frequency band(figs.1,2),
