The First Archaeomagnetic Age at Tiwanaku and Implications for Dating Andean Metallurgical Furnaces

Archaeometry, Volume 68, Issue 3, Page 317-329, June 2026.
ABSTRACT This paper presents the first archaeomagnetic dating at Tiwanaku (Andean Altiplano). We compared the geomagnetic field values recorded by a metallurgical furnace against an updated SHAWQ2k‐SH global model and a regional intensity curve, both of which include, for the first time, high‐quality intensity data from the Southern Hemisphere.

Mechanisms of Body Alignment in a Diurnal Songbird Migrant

Ethology, Volume 132, Issue 6, Page 399-411, June 2026.
The graphical abstract illustrates the body alignment mechanism of a diurnal songbird migrant, the dunnock (Prunella modularis). Dunnocks consistently expressed an angular body alignment, with inter‐individual variation at the level of the population.

Steady induction effects in geomagnetism. Part 1B: Geomagnetic estimation of steady surficial core motions: A non-linear inverse problem [PDF]

The problem of estimating a steady fluid velocity field near the top of Earth's core which induces the secular variation (SV) indicated by models of the observed geomagnetic field is examined in the source-free mantle/frozen-flux core (SFI/VFFC ...

A Recursive Truncated Taylor Expansion Downward Continuation Method for Geomagnetic Field

Applied Sciences
In aeromagnetic detection and geomagnetic navigation, the reference geomagnetic maps usually need to be continued to different altitudes. Traditionally, the geomagnetic field upward continuation is stable.

Regional and Seasonal Effects of Geomagnetic Storms on Terrestrial Weather

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract It has long been a mystery why small Total Solar Irradiation changes have significant effects on Earth's climate. Solar cycle correlation studies abound but cannot conclusively point to a viable physical mechanism. Here, I show that geomagnetic storms have a profound terrestrial weather impact.

Does the current minimum validate (or invalidate) cycle prediction methods? [PDF]

, 2010
This deep, extended solar minimum and the slow start to Cycle 24 strongly suggest that Cycle 24 will be a small cycle. A wide array of solar cycle prediction techniques have been applied to predicting the amplitude of Cycle 24 with widely different ...

Trapping of strangelets in the geomagnetic field

, 2007
Strangelets coming from the interstellar medium (ISM) are an interesting target to experiments searching for evidence of this hypothetic state of hadronic matter.

First Detection of the Two‐Dimensional Vertical Propagation of Traveling Ionospheric Disturbances Associated With Atmospheric Gravity Waves in the Martian Ionosphere

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract We report the detection of a traveling ionospheric disturbance (TID) captured by the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) Active Ionospheric Sounding (AIS) instrument aboard the Mars Express spacecraft at 150–250 km altitude.

Pymaginverse: A python package for global geomagnetic field modeling [PDF]

Applied Computing and Geosciences
Data-based geomagnetic models are key for mapping the global field, predicting the movement of magnetic poles, understanding the complex processes happening in the outer core, and describing the global expression of magnetic field reversals. There exists a wide range of models, which differ in a priori assumptions and methods for the interpolation of ...
