Geomagnetic History & Astrology

This is an educational snapshot, not an operational alert. At the 5:01 PM ET update, the field was quiet, with the magnetosphere somewhat expanded...

NASA's TRACERS results offer a fresh look at magnetic reconnection, where the solar wind's energy is released at Earth's magnetic shield. Field lines...

Observers' records and modern estimates answer different questions:

• Seen in 1859: Carrington and, independently, Hodgson saw a white-light...

Loess-paleosol sequences are described as key continental archives of environmental, climatic and geomagnetic variability. The available excerpt of...

A new study presents archaeomagnetic results from 29 combustion structures and 82 pottery fragments across 13 archaeological sites in Spain, with the...

An ancient Chinese record of a total solar eclipse on 17 July 709 BC offers new insights into how Earth's rotation has slowed over 2,700 years.

This paper treats bio-inspired magnetic navigation as an engineering problem. The Earth's field, sometimes described as "Nature's GPS", is presented...

The revised age places the Jordan Valley site hundreds of thousands of years earlier than previously believed.

• Old estimates were indirect: The...

A planned study at Kazan Federal University aims to use paleomagnetic analysis of loam samples from Kostenki–Borshchevo to reconstruct the field...

The 1871 account of an 1841 geomagnetic storm delaying an Exeter train was almost certainly misdated; railway records show the line opened only in...

This article details practical threats from solar-driven geomagnetic storms to power grids, satellites, GPS, and communications.

• Power grids face...

Ansell's mole rats display elevated activity in stress- and fear-linked brain regions, notably the amygdala, when exposed to a near-zero hypomagnetic...

Accurate Geomagnetic Polarity Time Scale construction is essential for reliably dating geological and biological events and reconstructing the history...

SEITEN couples the SUSANOO MHD model of CME propagation directly to the SEPIF particle-transport code through time-dependent shock conditions, then...

Observations confirm the turbulent dynamo's predicted spatial topology of stretched and folded magnetic fields, shaped by compressive effects and pressure-anisotropy instabilities.

Solar storms heat and expand the upper atmosphere, raising atmospheric drag that slows satellites, alters orbits, and reduces tracking accuracy. The...

• True polar wander moves Earth's geographic poles through crust-mantle reorientation, distinct from magnetic pole drift.
• Sea-level quadrant...

A simulation shows solar-wind magnetic field direction and Earth's tilt drive uneven waves along the magnetosphere's flanks, growing strongly on one...

The January 17–18, 2013 weak geomagnetic storm, examined via the GITM physics model, demonstrates how even minor storms couple into...

The Sun's magnetic activity has grown progressively confined to a shallow ~1,000 km layer since Cycle 23, diverging from surface metrics like sunspot...
