Eleven short bursts of data obtained during a 250 msec interval during the type III emission. Panels a and b give the X and Y components of the electric field in the spacecraft frame. Panel c gives the density fluctuations that are expected to accompany Langmuir waves. Panel d presents the angle in the X − Y plane between the background magnetic field and the electric field wave vector. The largest event, near 11:43:15.460, is discussed in the main text, and the small and medium size events near 11:43:15.450 and 11:43:15.580 are discussed in the appendix.
