The International Center for Space and Planetary Science is operating MAGDAS, a global observing network of fluxgate magnetometers. In FY2023, we established a first MAGDAS station in east Java, Indonesia, in cooperation with the University of Brawijaya. In addition, we conducted maintenance on existing stations in Malaysia, Egypt, and other countries. From next year onward, we plan to conduct maintenance in the Pacific Ocean and South American regions, and so on. We also conduct observations using induction magnetometers and FM-CW radar. As for the FM-CW radar, we are in the process of converting it to digital due to the aging of the equipment. In addition, we are developing a low-cost SDR-based scintillation detector for global ionospheric observations. Real-time plots and geomagnetic indices from MAGDAS data are available on our website. We have proposed the EE-index to monitor temporal and long-term variations of the equatorial electrojet by using magnetometer data around the equatorial region. We are also preparing to calculate and publish an index using magnetometer data in the Antarctic region. Our observational information, described in SPASE format, is provided from the IUGONET system. In addition, with the cooperation of the Kyushu University Library, we are in the process of registering these data in the university's repository. Through this work, MAGDAS data will be assigned DOIs. These tasks are scheduled to be completed by the end of FY2024. At the same time, we are renewing our website.
