A space environment data acquisition monitor (SEDA) has been flown onboard the Japanese meteorological satellites 'Himawari-8/9' as one of the housekeeping information monitors for satellite operation. SEDA consists of a high-energy proton sensor (SEDA-p) and a high-energy electron sensor (SEDA-e). These instruments provide near-real-time information on the conditions of the space environment on the Japanese meridian. Initial cross-comparison between SEDA and high-energy particle observation by geostationary operational environmental satellite (GOES) shows that the flux level of SEDA-e is slightly smaller than that of GOES observation, and the flux level of SEDA-p observation is a half that of GOES observation.
