Description

In 2024, major solar flares occurred in May and October, disrupting the radiation environment near Earth. This report presents the results of analyses of space radiation data and its effects in low Earth orbit and geostationary orbit obtained in 2024. GOSAT is equipped with a light particle telescope (LPT) for the purpose of high-energy charged particle environments that can cause spacecraft anomalies. This LPT is also equipped on JASON-3. These radiation monitors observed radiation belt behavior that differed from previous years. It also reports on changes in the altitudes of several JAXA low-altitude satellites. Discussions will be held on space weather in 2024 and its effects on satellites.
