Neural network prediction of geomagnetic activity: a method using local Hölder exponents [PDF]
, 2002 Local scaling and singularity properties of solar wind and geomagnetic time series were analysed using Hölder exponents . It was shown that in analysed cases due to the multifractality of fluctuations, α changes from point to point.

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).

Signs of a new geomagnetic jerk between 2019 and 2020 from Swarm and observatory data
Earth, Planets and Space, 2021 Highlights Observatory and Swarm data reveal a new geomagnetic jerk around 2019–2020. A very recent geomagnetic field model indicates the global character of the new jerk. A new pulse at the CMB around mid-2018 seems to be the starting point of this jerk.
