Geomagnetic field observations from 4 magnetic observatories located in Southern Africa located at Hermanus (HER), Hartebeesthoek (HBK), Keetmanshoop (KMH) and Tsumeb (TSU) have been analysed with the main purpose to identify abrupt secular variation chan... see more

Geomagnetic field observations from 4 magnetic observatories located in Southern Africa located at Hermanus (HER), Hartebeesthoek (HBK), Keetmanshoop (KMH) and Tsumeb (TSU) have been analysed with the main purpose to identify abrupt secular variation chan... see more

The static geomagnetic field of crustal origin is optionally calculated bythe recent global geomagnetic field models. However, their description in global scale tends to miss some local characteristics. The same can be inferred for the rate of the geomagn... see more

Geomagnetic secular variation, the generally slow, continuous change in the core magnetic field, is characterized by occasional rapid variations known as geomagnetic jerks. Recent studies on magnetic data obtained by satellites with a good globa... see more

The updated version of the ITalian Geomagnetic Reference Field (ITGRF) for 2000.0 and its secular variation modelup to 2005.0 are presented in this paper. The main field model is based on a simple polynomial approximation inlatitude and longitude of the g... see more

This paper examines the impact of secularization on marriages during Advent and Lent in two Flemish provinces (West-Flanders and Flemish-Brabant) and Brussels-capital. The evolution of the level of church control of the marriage ban (a measure of the proc... see more

In Italy INGV (Istituto Nazionale di Geofisica e Vulcanologia) has systematically undertaken the task of periodic making measurements of the Earth's magnetic field on a network of more than 110 points (repeat stations), with an average spacing around 55-6... see more

A magnetic induction model has been applied to recordings obtained in 2010 during the field campaigns for geomagnetic measurements at the 26 repeat stations of the Romanian secular variation network. The model is based on the observation that a variable e... see more

The Istituto Nazionale di Geofisica e Vulcanologia (INGV) has systematically undertaken the task of making measurements of the Earth's magnetic field in Italy. By tradition and because of the elongated geometric shape of our peninsula and islands, in Ital... see more
