与1972年8月太阳耀斑相关的冲击波的形状是通过比较来自Prognoz，Prognoz 2，先锋9和先锋10空间探测器的等离子体测量数据与射电源闪烁和彗星亮度的观测来确定的。8月2日的两个耀斑得到了近似球形的激波形式，8月4日和7日的耀斑得到了基本上非球形的激波形式。根据Prognoz 2对每个冲击波后面的附加能量和质量通量的测量，确定的能量和喷射质量分别为1032-1033尔格和1016-1017克。通过比较Prognoz 2和Pioneer 9的观测资料，我们推断出8月4日耀斑在激波阵面上耀斑子午线附近有一个显著的最大能量通量。
The shape of the shock waves associated with the August 1972 solar flares was determined by comparing the plasma measurement data from the Prognoz, Prognoz 2, Pioneer 9, and Pioneer 10 space probes with observations of radio source scintillations and comet brightness. A nearly spherical shock wave form was obtained for two flares on August 2, and essentially nonspherical shock wave forms were obtained for flares on August 4 and 7. The energy and ejected mass determined from the Prognoz 2 measurements of the additional energy and mass flux behind each shock wave are 1032–1033 ergs and 1016–1017 g, respectively. From the comparison of Prognoz 2 and Pioneer 9 data a significant maximum energy flux near the flare meridian on the shock wave front was deduced for the August 4 flare.
