Since ancient times, solar eclipses have fascinated-and some-times terrified-humankind. Solar eclipses are direct sensory ex-periences. As the sun vanishes from the sky, birds fall silent dur-ing the midday twilight. Modern instrumentation has enabled re-search into the consequences of this sudden change in irradi-ation within the upper atmosphere. For the first time in 26 years, atotal solar eclipse occurred over the continental United States（CONUS） on 21 August 2017, passing between coastlines in the16：00–20：00 UT period. Millions of citizens and science enthusi-asts lined up from Oregon all the way to the South Carolina alongthe 150 km wide path of totality to witness moments of amazingsurreality during this event.
