arnoldyuki@serc.kyushu-u.ac.jp The Space Environment Research Center (SERC), Kyushu University (KU), conducts everyday space weather “now casting”. There are two main goals in this effort: (1) to train and educate KU students about the complexities of the Sun-Earth system so that they can become space weather forecasters in the future, (2) to globally disseminate space weather information from SERC as a service to the scientific community and the general public. In order to understand the complexities of the Sun-Earth system, KU students analyze the data of four regions: (1) solar surface, (2) solar wind, (3) geospace, and (4) the Earth’s surface. Using real-time public data from SOHO Real Time Movies, Solar Monitor, NASA/GSFC/SDAC, and SEC‘s Anonymous FTP Server, they check each day the Sun Spot Number, locations of active regions and coronal holes, and identify solar flare events: GOES X-Ray Flux, CME: SOHO/ LASCO- C2, 3, and Proton Event: GOES Proton Flux. By analyzing ACE Real Time Data, KU students examine the solar wind (Speed, Density, Temperature) and Interplanetary Magnetic Field (IMF: Bt, Bz, Phi), and identify events of sector boundary, CIR, CME, and Shock/Discontinuity. To understand magnetic circumstances in geospace and on the Earth’s Surface, KU students analyze storms and substorms using Dst index (Kyoto Univ.), Kp index (NOAA), and Magnetic Pulsation Index (Pc 3, 4, and 5: SERC). Every morning KU students create a space weather report and then discuss it with the staff at SERC for local training and education. The report and its details are disseminated on the SERC Home Page (http://www.serc.kyushu-u.ac.jp) to provide "global outreach" for space weather information. MAGDAS (Magnetic Data Acquisition System) data are obtained from the Circum-pan Pacific Magnetometer Network (CPMN) locations during the IHY period (2007-2008). MAGDAS magnetometers are installed at 50 stations along the 210o magnetic meridian and the magnetic dip equator, which includes East Asia, the Pacific Islands, South America and Africa. MAGDAS data is made up of three components of the magnetic variations (H, D, Z) with 1-second and 1- minute sampling rate. After data correction at SERC, authorized MAGDAS collaborators can access the SERC server, in which the corrected data are stored, and get 1-min and 1-sec digital data. The MAGDAS data can be provided for all the scientific purposes through the Internet. SERC will offer the MAGDAS database to the scientific community for collaborative work.
