The GOES-19 satellite, which joined the NOAA fleet of meteorological instruments in June 2024, captures images of the outer layer of our star's atmosphere using the advanced CCOR-1 coronagraph.
The coronagraph appears in the photograph as a dark circle that blocks the brightest light from the Sun.
CCOR-1 monitors the solar corona to predict coronal mass ejections, which are massive clouds of solar plasma infused with magnetic field lines that are released from the Sun during intense, prolonged solar flares.
At times, coronal mass ejections are directed towards Earth and can reach it. Such events lead to the formation of bright auroras and geomagnetic storms, which can disrupt the operation of satellites, navigation systems, and electrical grids on the planet.
