The quiet daily variations of the geomagnetic field (S q ) have been studied by using the geomagnetic data of the 10 International Quietest Days. Geomagnetic data from MAGDAS I and II stations - ten stations were selected around the 96° magnetic meridian (MM) - over Africa have been analyzed from September 2008 to August 2009. The analysis of this unique data set clarifies the characteristics of the S q variations over the African sector for the first time by observational geomagnetic data. In this paper, we found that S q (H) and S q (D) show a predominantly annual variation. The most interesting result, and a new finding in the African sector, is the appearance of two vortices in the day lit southern hemisphere during spring. Further data analysis also revealed many other interesting characteristics for the S q over the African sector.

Pi 2 waves simultaneously observed by Cluster and CPMN ground-based magnetometers near the plasmapause 査読有り国際誌

We have analyzed an event on 14 February 2003 in which Cluster satellites and the CPMN ground magnetometer chain made simultaneous observations of a Pi 2 pulsation along the same meridian. Three of the four Cluster satellites were located outside the plasmasphere, while the other one was located within the plasmasphere. By combining the multipoint observations in space and the multipoint observations on the ground, we have obtained a detailed L-profile of the Pi 2 signatures, which has not been done in the past. In addition, we have used a method called Independent Component Analysis (ICA) to separate out other superposed waves with similar spectral components. The result shows that the wave phase of the Pi 2 was the same up to L &sim; 3.9 (corresponding to the plasmasphere), became earlier up to L &sim; 4.1 (corresponding to the plasmapause boundary layer), and showed a delaying tendency up to L &sim; 5.9 (corresponding to the plasmatrough). This systematic phase pattern, obtained for the first time by a combination of a ground magnetometer chain and multisatellites along a magnetic meridian with the aid of ICA, supports the interpretation that a Pi 2 signal propagated from a farther source and reached the plasmasphere. © Author(s) 2011.
