There have been several observations of weak flare-like events on the sun, generically termed "microflares." Such phenomena are theoretically interesting for several reasons. This grant will examine the distribution functions of flare occurrence, using several time series that reflect different aspects of flare physics. One tool will be the use of model time series generated by Monte Carlo simulation. The objectives will be to relate "microflare" phenomena observed during MAX 91 to the distribution functions of events in the normal range, and to draw inferences about use of weak non- thermal events as elements of coronal heating. Observations from the solar maximum period are better for microflare studies because of the generally higher activity levels.

在太阳上有几种观察到类似耀斑的事件的观察，通常称为“微丝”。 这种现象在理论上很有趣，原因有几个。 该赠款将使用反映耀斑物理学不同方面的几个时间序列来检查耀斑发生的分布功能。 一种工具将是使用蒙特卡洛模拟生成的模型时间序列。 这些目标将是将在最大91期间观察到的“微叶片”现象与正常范围内事件的分布函数相关联，并提出有关使用弱非热事件作为冠状加热元素的推断。 由于通常较高的活性水平，从太阳能最大周期进行的观察结果更好。
