Some reports have suggested that epileptic seizures might occur more frequently at times of enhanced disturbance of the geomagnetic field. This study examines this putative association using 4101 seizures from 22 epileptic patients where the seizure times were known to within a day or better. A measure of the geomagnet-ic fluctuation level for the seizure day, and the days preceding the seizure...

We conduct a statistical analysis of the coherence and phase difference of low frequency geomagnetic fluctuations between two Antarctic stations, Mario Zucchelli Station (geographic coordinates: 74.7 S, 164.1 E; corrected geomagnetic coordinates: 80.0 S, 307.7 E) and Scott Base (geographic coordinates: 77.8 S 166.8 E; corrected geomagnetic coordinates: 80.0 S 326.5 E), both located in the polar...

Geomagnetic disturbance forecasting is based on the identification of solar wind structures and accurate determination their magnetic field orientation. For nowcasting activities, this currently a tedious manual process. Focusing main driver geomagnetic disturbances, twisted internal interplanetary coronal mass ejections (ICMEs), we explore convolutional neural network’s (CNN) ability to predic...

Data on the relation of past climate variations and changes in the geomagnetic +eld can contribute to the research on a cosmic ray–climate link. This paper presents a synthesis of geological and astrophysical results about the link of magnetic +eld variations and Earth’s climate and external forcing. On millennial timescales, geomagnetic intensity lows are apparently in phase with times of low ...

The influence of the geomagnetic field on the development of air showers is studied. The well known International Geomagnetic Reference Field was included in the AIRES air shower simulation program as an auxiliary tool to allow calculating very accurate estimations of the geomagnetic field given the geographic coordinates, altitude above sea level and date of a given event. Some test simulation...

The large decrease in the horizontal component of the earth's field during the main phase of magnetic storms has been ascribed to the formation or enhancement of a geomagnetic ring current. In this paper we discuss the motions of particles trapped in the earth's dipole field and the resulting ring current. These calculations deal only with a steady state, though during storms the state is chang...

Fritz [see 7 of "References" at end of paper] in a famous memoir published in 1881 discussed the frequency and characteristics of aurora observed in the Northern Hemisphere during the years 1700 to 1872. Using observations during this 172-year period [8] he also constructed his well-known map of isochasms of equal auroral frequency. Beginning is made here in the statistical analysis of the auro...
