                       A Total Solar Eclipse Reflected

   Explanation: If you saw a total solar eclipse, would you do a
   double-take? One astrophotographer did just that -- but it took a lake
   and a bit of planning. Realizing that the eclipse would be low on the
   horizon, he looked for a suitable place along the [4]thin swath of
   South America that would see, for a few minutes, the Moon completely
   block the Sun, both directly and in reflection. The day before
   totality, he visited a lake called [5]La Cuesta Del Viento (The Slope
   of the Wind) and, despite its name, found so little wind that the lake
   looked like a mirror. [6]Perfect. Returning the day of the eclipse,
   though, there was a strong breeze [7]churning up the water -- enough to
   ruin the eclipse reflection shot. [8]Despair. But wait! Strangely,
   about an hour before [9]totality, the wind died down. This calmness may
   have been related to the eclipse itself, because [10]eclipsed ground
   heats the air less and reduces the amount rising warm air -- which can
   dampen and even change the wind direction. The [11]eclipse came, his
   tripod and camera were ready, and so was the lake. The featured image
   of this [12]double-eclipse came from a single exposure lasting just one
   fifteenth of a second. Soon after [13]totality, the winds returned and
   the water again became choppy. No matter -- this double-image of the
   [14]2019 July total solar eclipse had been captured forever.
