Using high spatial- and temporal-resolution images acquired with the Clark Lake multifrequency radioheliograph, we will study meter-decameter radio sources in the solar corona. Radio synoptic charts and quiet Sun maps will be used to study and model large-scale structures such as streamers and coronal holes. Impulsive burst observations will be used in conjunction with soft X-ray data to study several aspects of coronal mass ejections, including structure and plasma parameters, height-time evolution, the relationship of CME's, flare and shocks, and acceleration of particles at slow shocks. The overall aim is to use already existing data to elucidate the nature of impulsive ejections from the sun which ultimately impact the earth.

使用Clark Lake Multefrequency RelefleeHeliograph获取的高空间和时间分辨率图像，我们将研究太阳能电晕中的仪表指示表。 无线电天气图和安静的太阳图将用于研究和建模大规模结构，例如彩带和冠状孔。 冲动性爆发观测将与软X射线数据结合使用，以研究冠状质量弹出的几个方面，包括结构和等离子体参数，高度时间的演变，CME的关系，耀斑和冲击以及慢速冲击处颗粒的加速度。 总体目的是使用已经存在的数据来阐明最终影响地球的太阳冲动弹出的性质。
