这张3月27日拍摄的建筑和日落的长焦照片，是在朦胧的大气的自然滤镜下拍摄的。太阳活动区2975和2976的大黑子在太阳圆盘的映衬下，被挤在比萨大教堂和著名的斜塔之间。仅仅一天之后，凝视太阳的宇宙飞船就观测到2975活跃区释放出疯狂的太阳耀斑以及两次日冕物质抛射。最大的一次在3月31日撞击了磁层，引发了高纬度夜空的地磁风暴和极光。3月30日，2975活动区再次爆发了一次强大的x级太阳耀斑，导致地球上的无线电暂时中断。

The natural filter of a hazy atmosphere offered this recognizable architecture and sunset telephoto view on March 27. Dark against the solar disk, large sunspots in solar active regions 2975 and 2976 are wedged between the Duomo of Pisa and its famous Leaning Tower. Only one day later, Sun-staring spacecraft watched active region 2975 unleash a frenzy of solar flares along with two coronal mass ejections. The largest impacted the magnetosphere on March 31 triggering a geomagnetic storm and aurorae in high-latitude night skies. On March 30, active region 2975 erupted again with a powerful X-class solar flare that caused a temporary radio blackout on planet Earth.
