Measurements of solar energetic protons at 07:30 UT on 11 September 2017. The data from the new instruments on GOES-R is shown in red, while the other lines show data from the older NOAA GOES weather satellites. The data are well cross-calibrated, and the new instruments provide both improved energy coverage and a higher fidelity measurement enabling new science and improving space weather monitoring.

Solar energetic particle events, where energetic protons erupting from the Sun reach near-Earth space, are a hazard for both satellites and astronauts. NOAA’s newest series of weather satellites has updated space weather sensors to provide improved monitoring of this hazard. A series of solar energetic particle events in September 2017 provided an opportunity to cross-compare the measurements with instruments from previous generations. Kress et al. [2021] introduce the new data set, showcase the improved capabilities for operations and scientific discovery, and enable exceptionally long baseline measurements for understanding long term trends in solar eruptions.
