Coronal shocks associated with CMEs and flares and their space weather consequences

, 2010
We study the geoeffectiveness of a sample of complex events; each includes a coronal type II burst, accompanied by a GOES SXR flare and LASCO CME. The radio bursts were recorded by the ARTEMIS-IV radio spectrograph, in the 100-650 MHz range; the GOES SXR

Late‐Holocene evolution of a small Sub‐Arctic glacier, Gljúfurárjökull (Tröllaskagi, northern Iceland)

Boreas, EarlyView.
Gljúfurárjökull, located on the Tröllaskagi Peninsula in northern Iceland, is a small glacier approximately 3.8 km in length. This study analyses the glacier's evolution through a combination of methods including: (i) geomorphological mapping, (ii) Cosmic‐Ray Exposure (CRE) dating, (iii) lichenometry and (iv) palaeoglacier reconstruction (volume ...

Method for estimation of solar, geomagnetic, and atmospheric contributions to 27-day component of peak electron density

Results in Physics, 2019
The study suggests a new method for estimation of the solar, geomagnetic, and atmospheric contributions to 27-day component of peak electron density. For our analysis, we calculated complex amplitudes of 27-day components filtered from the data sets of ...

On the validation of K-index values at Italian geomagnetic observatories [PDF]

Geoscientific Instrumentation, Methods and Data Systems, 2020
The local K index and the consequent global Kp index are well-established 3 h range indices used to characterize geomagnetic activity. The K index is one of the parameters that INTERMAGNET observatories can provide, and it has been widely used for

A supramolecular assembly of cone‐specific G‐protein and cryptochrome 4a on lipid bilayer

The FEBS Journal, EarlyView.
Immobilized phospholipid bilayers on a sensor chip surface serve as membrane platform to investigate critical protein–lipid and protein–protein interaction processes by surface plasmon resonance. The putative magnetoreceptor cryptochrome 4a and the myristoylated cone‐specific G‐protein α‐subunit (Gtα) bind with high affinity to immobilized lipid ...

A Novel Neural Network‐Based Approach to Derive a Local Geomagnetic Baseline for Future Robust Characterization of Geomagnetic Indices at Mid‐Latitude

Space Weather
Geomagnetic indices derived from ground magnetic measurements characterize the intensity of solar‐terrestrial interaction. Global magnetic indices derived from multiple magnetic observatories at mid‐latitude have commonly been used for space weather ...
