The Earth magnetosphere simulation is continuously running in real-time for space weather in the National Institute of Information and Communications Technology (NICT). Code of this simulation was originally developed by Tanaka (JGR, 1995) and was implemented as one of the NICT real-time space weather simulations by Den et al. (Space Weather, 2006). The space weather cloud computing system has a distributed large storage system and a data analysis system and has been constructed in the NICT. Using this space weather cloud computing system, it becomes possible to preserve the result of the real-time magnetosphere simulation. It enables to analyze the response of the magnetosphere for various solar wind conditions. There are several works on the real-time simulation using AE index (Kitamura et al., JGR, 2008), the polar cap potential (Kunitake et al, Journal of NICT, 2009), the plasma environment at gestational orbit (Nakamura et al., Journal of NICT, 2009). In this analysis, we focused magnetic variation at gestational orbit and location of magnetopause. At gestational orbit, there are continuous magnetic field observations by the GOES satellites. On magnetopause location, there is an empirical model called the Shue model, which takes account of dynamic pressure and south-ward IMF of solar wind. We compared the result of the real-time simulation with magnetic field variations observed by the GOES satellites and magnetopause location calculated by the Shue model. We will report the result of this study.
