A Study of Low-Latitude Pulsating Auroras During the Maaximum of Solar Cycle 22

该基金用于基础磁层等离子体研究 物理学和极光的本质。 特别是， 用于注入和去除外区的磁脉动 被捕获的货车艾伦带电子将被研究。 意见 低纬度极光事件的脉动阶段， 使用高灵敏度光度计测量太阳活动22周的极大值， 在明尼阿波利斯的相关数据将继续和扩大， 将低亮度级TV图像添加到所述数据集以产生 脉动形式的永久图像。 这些脉动开始 在极光解体时， 早上 这种相互作用被认为是由于 货车艾伦电子与冷等离子体相互作用 产生不稳定性和沉淀。

This grant is for research in basic magnetospheric plasma physics and the nature of the aurora. In particular, the role of magnetic pulsations for the injection and removal of outer zone trapped Van Allen belt electrons will be studied. Observations of the pulsation phase of low-latitude auroral events during the maximum of solar cycle 22 using high sensitivity photometers and correlated data at Minneapolis will be continued and expanded by adding low-light-level TV images to the data set to produce permanent images of the pulsating forms. These pulsations begin at auroral breakup and often continue for many hours into the morning. This interaction is thought to be due to the interaction of Van Allen outer zone electron with cold plasma producting instabilities and precipitation.
