2020年4月19日，太阳轨道器在0.8 Au的日心距离处探测到CME，并于4月20日由Wind和BepiColombo进行了现场观测。在此期间，BepiColombo刚刚完成了对地球的飞越，因此BepiColombo和Wind之间的纵向距离仅为1.4。太阳轨道器和两个航天器在地球附近的总纵向间隔小于5，为CME的径向对准研究提供了极好的机会。我们使用的磁场在太阳轨道器与那些在风和BepiColombo的现场观测分析的大规模的属性的CME和比较结果预测使用远程观测在STEREO-A，提供一个全球图片的CME，因为它从太阳传播到1 Au。
On April 19th 2020 a CME was detected by Solar Orbiter at a heliocentric distance of 0.8 AU and was also observed in-situ on April 20th by both Wind and BepiColombo. During this time, BepiColombo had just completed a flyby of the Earth and therefore the longitudinal separation between BepiColombo and Wind was just 1.4°. The total longitudinal separation of Solar Orbiter and both spacecraft near the Earth was less than 5°, providing an excellent opportunity for a radial alignment study of the CME. We use the in-situ observations of the magnetic field at Solar Orbiter with those at Wind and BepiColombo to analyse the large-scale properties of the CME and compare results to those predicted using remote observations at STEREO-A, providing a global picture of the CME as it propagated from the Sun to 1 AU.
