   Explanation: The natural filter of a hazy atmosphere offered this
   recognizable architecture and sunset 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 [5]famous Leaning Tower. Only
   one day later, [6]Sun-staring spacecraft watched active region 2975
   unleash a [7]frenzy of solar flares along with two coronal mass
   ejections. The largest impacted the magnetosphere on March 31
   triggering a geomagnetic storm and [8]aurorae in high-latitude night
   skies. [9]On March 30, active region 2975 erupted again with a powerful
   [10]X-class solar flare that caused a temporary radio blackout on
   planet Earth.
