Modeling of geocoronal solar wind charge exchange events detected with Suzaku

A model of geocoronal solar wind charge exchange (SWCX) emission was built and compared to five Suzaku detections bright SWCX events. An exospheric neutral hydrogen distribution model, cross sections, ion data taken with the ACE WIND satellites, magnetic field models Earth's magnetosphere are all combined in order predict time-variable depending on line-of-sight directions satellite. The modeled average intensities O VII lines were consistent observed ones within a factor three four out cases except for an event which direction toward night side high-latitude magnetosheath major geomagnetic storm observed. Those VIII underestimated by or more cases. On other hand, light curves reproduced after being scaled ratios between intensities. In particular, short-term variations due traversing cusp regions during orbital motion satellite reproduced. These results discussed context uncertainties.
