Abstract Solar disturbances produce major effects on the corona, the solar wind, the interplanetary medium, and the Earth along with its magnetosphere. New techniques have been developed for studying plasma disturbances in the inner heliosphere. This research will continue to investigate the physics of these disturbances, using data from the HELIOS zodiacal-light photometers and a variety of other coronal instruments. The zodiacal-light photometers have already provided the first stereoscopic information about the heliospheric shape of these disturbances. Modelling techniques will also be employed to interpret and fit the observed results. The HELIOS imaging combined with other observations should provide a unique opportunity to determine coronal mass-ejection velocities, streamer material velocities, 3D structures, and total masses in the interplanetary medium. This can be done with fewer assumptions and more accuracy than previously possible. Besides mass ejections, solar disturbances which reach the interplanetary medium also include coronal streamers, shocks, and co-rotating interaction regions, It has been possible to view these features with the zodiacal-light photometers on board the HELIOS spacecraft and these will be studied to determine how they relate to near-surface solar structures and the heliospheric current sheet. The study will be extended to include comparisons of the HELIOS photometer observations with other remote sensing observations including those of kilometric radio bursts and interplanetary scintillations provided by the Cambridge, England scintillation array. *** //

抽象的太阳干扰对电晕，太阳风，星际介质和地球及其磁层产生重大影响。 已经开发了用于研究内层中血浆障碍的新技术。 这项研究将继续使用来自Helios黄道灯光光度计和各种其他冠状动脉仪器的数据来研究这些干扰的物理。十二生座光度计已经提供了有关这些干扰的地球层形状的第一个立体信息。 还将采用建模技术来解释和拟合观察到的结果。 HELIOS成像与其他观察结果相结合，应提供独特的机会，以确定星际间介质中的冠状质量驱动速度，流媒体材料速度，3D结构和总质量。 这可以用比以前可能更少的假设和更准确的方法来完成。 除了大规模弹出外，到达行星际介质的太阳能干扰还包括冠状流媒体，冲击和共旋转的交互区域，可以通过Helios spacecraft上的Zodiacal-Light光度计查看这些功能，并将研究这些功能，以确定它们与近距离太阳能结构和近距离太阳能结构和螺旋型的相关性。 该研究将扩展到包括对Helios光度计观测值与其他遥感观测值的比较，包括千分之光的无线电爆发和英格兰闪烁阵列剑桥提供的星际闪烁。 *** //
