As Chile and Argentina witnessed the total solar eclipse on Dec. 14, 2020, unbeknownst to skywatchers, a little tiny speck was flying past the Sun — a recently discovered comet.
This comet was first spotted in satellite data by Thai amateur astronomer Worachate Boonplod on the NASA-funded Sungrazer Project — a citizen science project that invites anyone to search for and discover new comets in images from the joint European Space Agency (ESA) and NASA Solar and Heliospheric Observatory, or SOHO.
Boonplod discovered the comet on Dec. 13, the day before the eclipse. He knew the eclipse was coming, and was eager to see whether his new comet discovery might appear in the Sun’s outer atmosphere as a small speck in eclipse photographs.
