SUVI calendar heatmap
Introduction The Solar Ultraviolet Imager (SUVI) aboard NOAA’s GOES takes pictures of the Sun in 6 ultraviolet passbands. They’re quite stunning and are used for space weather monitoring and prediction. (I was lucky enough to get to work with them in my previous job at NOAA.) To make them more useful, the imager takes long and short length exposures and then composites them together as a Level 2 composite image product.
