The driving mechanisms of particle precipitation during the moderate geomagnetic storm of 7 January 2005 [PDF]
, 2007 International audienceThe arrival of an interplanetary coronal mass ejection (ICME) triggered a sudden storm commencement (SSC) at ~09:22 UT on the 7 January 2005. The ICME followed a quiet period in the solar wind and interplanetary magnetic field (IMF).

Development of a Systematic Model for Study on the Phenomena of Ionospheric and Geomagnetic Variations [PDF]
Journal of Astronomy and Space Sciences, 1999 Solar activities ejecting high energy particles influence satellites and satellite communications as well as perturb geomagnetic fields. To understand space environments near the Earth being influenced by the Sun, we must study about the magnetosphere ...

Correction of artificial jumps in the historical geomagnetic measurements of Coimbra Observatory, Portugal [PDF]
Annales Geophysicae, 2014 The Coimbra Magnetic Observatory (International Association of Geomagnetism and Aeronomy code COI) in Portugal has a long history of observation of the geomagnetic field, spanning almost 150 yr since the first geomagnetic measurements in 1866.

Determination of a steady velocity field in a rotating frame of reference at the surface of the Earth's core [PDF]
, 1996 We relax the steady-motions theorem by solving for a steady velocity field at the surface of the core in a frame of reference drifting at a linear rate with respect to an observer fixed in the mantle frame of reference.
