Satellite Measured Ionospheric Magnetic Field Variations over Natural Hazards Sites [PDF]

Remote Sensing, 2021
Processes and threats related to natural hazards play an important role in the evolution of the Earth and in human history. The purpose of this study is to investigate magnetic field variations measured at low Earth orbit (LEO) altitudes possibly ...

On the Characterization of GJ 504: A Magnetically Active Planet-host Star Observed by the Transiting Exoplanet Survey Satellite (TESS)

The Astrophysical Journal, 2022
Abstract We present the results of the analysis of the photometric data collected in long- and short-cadence mode by the Transiting Exoplanet Survey Satellite for GJ 504, a well-studied planet-hosting solar-like star, whose fundamental parameters have been largely debated during the last decade.

Geodynamic Aspects of Magnetic Data Analysis and Tectonic–Paleomagnetic Mapping in the Easternmost Mediterranean: A Review

Applied Sciences, 2023
The Easternmost Mediterranean is a transition region from the ocean to the continent where the spreading and collision zones of the lithospheric plates join.

Contemporaneous Observations of Hα Luminosities and Photometric Amplitudes for M Dwarfs

The Astronomical Journal, 2023
While many M dwarfs are known to have strong magnetic fields and high levels of magnetic activity, we are still unsure about the properties of their starspots and the origin of their magnetic dynamos.

Crustal analysis of maud rise from combined satellite and near-surface magnetic survey data [PDF]

Earth, Planets and Space, 2005
Abstract We produced a crustal magnetization model for the Maud Rise in the southwest Indian Ocean off the coast of East Antarctica using magnetic observations from the Ørsted satellite and near-surface surveys complied by the Antarctic Digital Magnetic Anomaly Project (ADMAP).

Ionospheric currents estimated simultaneously from CHAMP satelliteand IMAGE ground-based magnetic field measurements: a statisticalstudy at auroral latitudes [PDF]

Annales Geophysicae, 2004
One important contribution to the magnetic field measured at satellite altitude and at ground level comes from the external currents. We used the total field data sampled by the Overhauser Magnetometer on CHAMP and the horizontal magnetic field ...

Determining Residual Deviation and Analysis of the Current Use of the Magnetic Compass

Journal of Marine Science and Engineering, 2021
The use of electronic compasses and satellite systems has led to the magnetic compass becoming a secondary means of navigation. Yet this means of navigating is not only not obsolete, it is a necessary backup device: the construction simplicity of the ...

Excess open solar magnetic flux from satellite data: 2. A survey of kinematic effects [PDF]

Journal of Geophysical Research: Space Physics, 2009
We investigate the “flux excess” effect, whereby open solar flux estimates from spacecraft increase with increasing heliocentric distance. We analyze the kinematic effect on these open solar flux estimates of large‐scale longitudinal structure in the solar wind flow, with particular emphasis on correcting estimates made using data from near‐Earth ...

Filamentary field-aligned currents at the polar cap region during northward interplanetary magnetic field derived with the Swarm constellation [PDF]

Annales Geophysicae, 2016
ESA's Swarm constellation mission makes it possible for the first time to determine field-aligned currents (FACs) in the ionosphere uniquely. In particular at high latitudes, the dual-satellite approach can reliably detect some FAC structures which ...
