During the 21st solaractivitycycle the HXEBS aboard SMM satellite and the HXM on HINOTORI spacecraft detected several thousand hard X-ray solar flares.
The frequency shifts is found to increase with the strength of magnetic fields in solar interior, and its temporal behavior closely follows the phase of the synthetic solaractivitycycle.
我们发现频率的变化随着太阳内部磁场强度增加而变大,并且和太阳活动周期密切相关。

The scientists concluded that the solar wind activity must follow the same cycle.
