Abstract
Two remarkable intensity-time patterns in the 113 and 64 MHz single-frequency radio flux records during a type I noise storm and/or a type IV burst on 31 July, 1983 are studied. A comparison of the patterns at both frequencies reveals a high degree of resemblance and inherent common structure although the 64 MHz pattern was seen 40 min later than the 113 MHz pattern. An interpretation is given assuming a slowly uprising and thereby expanding clumpy plasma-magnetic field configuration which is (via accompanying coronal loops) two times illuminated by energetic electrons coming from the soft X-ray flare precursor source region of the H-alpha flares F1 and F2 (see Figure 1).
