A Rocket in the Sun

Explanation: On the morning of September 24 a rocket crosses the bright solar disk in this long range telescopic snapshot captured from Orlando, Florida. That’s about 50 miles north of its Kennedy Space Center launch site. This rocket carried three new space weather missions to space. Signals have now been successfully acquired from all three – NASA’s Interstellar Mapping and Acceleration Probe, NASA’s Carruthers Geocorona Observatory, and the National Oceanic and Atmospheric Administration (NOAA) Space Weather Follow-On Lagrange 1 (SWFO-L1) – as they begin their journey to L1, an Earth-Sun lagrange point. L1 is about 1.5 million kilometers in the sunward direction from planet Earth. Appropriately, major space weather influencers, aka dark sunspots in active regions across the Sun, are posing with the transiting rocket. In fact, large active region AR4225 is just right of the rocket’s nose.

说明: 在9月24日的早晨，一枚火箭穿越明亮的太阳圆盘，这张长距离望远镜快照是在佛罗里达州奥兰多拍摄。这距离甘迺迪太空中心发射场以北约50英里。这枚火箭将三个新的太空天气任务送入太空。现在，已经成功从这三个任务中获取信号，包含了-NASA的星际测绘和加速探测器(IMAP)、NASA的卡鲁瑟斯地冕天文台以及美国国家海洋和大气管理局（NOAA）的太空天气后续拉格朗日1号（SWFO-L1）-它们开始了前往L1，即地日拉格朗日点的旅程。L1距离地球约150万公里，位于朝向太阳的方向。恰如其分的是，主要的太空天气影响因素，即太阳活跃区域中的黑子，正与穿越的火箭合影。事实上，大型活跃区AR4225就在火箭的鼻尖右侧。
