NOAA's new GOES-19 satellite continuously monitors solar activity, to protect satellites, communications & electrical systems. (It also regularly catches the Earth & Moon photobombing its view of the Sun.)
One small example of what NOAA funding does...

1. This video, captured by CCOR-1, shows the sun’s corona. The sun’s size is indicated by the small empty circle, and the instrument blocks most of the sun’s light using a dark disk that is almost four times wider. This allows fainter structures, like CMEs, to be detected. CMEs are seen as bright wispy plasma clouds expanding away from the dark disk. Twice a day, there is a flash due to the Earth “photobombing” the CCOR-1 field of view. The flash, or ‘earthshine’, is due to the strong reflection of sunlight from our oceans and clouds. Furthermore, the moon passes through the image approximately once a day and is brightly lit due to the same reflection off the planet’s surface.
