New Data from NOAA GOES-16's Space Environment In-Situ Suite (SEISS) Instrument (image) NASA/Goddard Space Flight Center Share Print E-Mail Caption This plot of SEISS data shows injections of protons and electrons observed by the Magnetospheric Particle Sensors MPS-HI and Solar and Galactic Proton Sensor (SGPS) on Jan. 19, 2017. MPS-HI and SGPS are two of the individual sensor units on SEISS. The fluxes shown are from the MPS-HI telescopes that look radially outward from the Earth, and from the lowest-energy channel observed by the eastward-looking SGPS.
