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.

对太阳上的弱耀斑事件有过几次观测，通常被称为“微耀斑”。从理论上讲，这种现象很有趣，原因有几个。这笔赠款将使用反映耀斑物理不同方面的几个时间序列来研究耀斑发生的分布函数。一种工具是使用蒙特卡罗模拟产生的模型时间序列。目标是将在MAX 91期间观察到的“微耀斑”现象与正常范围内事件的分布函数联系起来，并推断使用微弱的非热事件作为日冕加热的元素。太阳活动高峰期的观测结果更适合微耀斑研究，因为它们的活动水平普遍较高。
