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.  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.
