December 14, 2020 – Total EclipseCompound image from 65 originals from Andreas Möller at Piedras del Aguila made by Roman Vanur/Jay Pasachoff, including a coronal mass ejection (CME) at left and an eclipse comet, Comet/SOHO-4108, also observed from U.S. Naval Research Laboratory’s C2 coronagraph on the European Space Agency’s Solar and Heliospheric Observatory (SoHO) and with NASA’s STEREO-B spacecraft.

Comet C/2020 X3 (SOHO)
The comet, is named/numbered courtesy of Karl Battams, Solar and Heliospheric Physics Branch, US Naval Research Laboratory, with orbit discussed with the Minor Planet Center of the International Astronomical Union based at the Harvard-Smithsonian Center for Astrophysics: Bill Gray, Dan Green, Federica Spoto/Matt Holman. It was spotted on a SoHO LASCO/C2-coronagraph image by Worachate Boonplod, one of the citizen scientists known as SOHO comet hunters. It also shows on a COR-2 image from NASA’s STEREO-A COR-2 coronagraph.
