AB: GEONET is the dense GPS receiver network in JAPAN. The data have been used to derive TEC to study ionospheric disturbances in NICT. Quick distribution of the data, within a few hours, has been started recently. We have developed a new method of prompt derivation of TEC from the data and use the TEC distribution over Japan in our daily operation of Space Weather Forecast Center at NICT (RWC Japan of ISES). We will present the outline of the system of prompt derivation of TEC, its performance results, and its capability of monitoring the ionosphere over Japan with some specific events of ionospheric disturbances.
