This is an attempt to identify the causes of geomagnetic storms which occurred during a year and a half from January 1977 to June 1978. The assignment of geomagnetic storm causation to appropriate coronal holes or solar flares has been made by ...

Unexpected space weather causing the reentry of 38 Starlink satellites in February 2022
The accidental reentry of 38 Starlink satellites occurred in early February 2022, associated with the occurrence of moderate magnetic storms. A poorly understood structure of Coronal Mass Ejections (CMEs) caused the magnetic storms at unexpected timing ...

Dst Prediction Based on Solar Wind Parameters [PDF]
We reevaluate the Burton equation (Burton et al. 1975) of predicting Dst index using high quality hourly solar wind data supplied by the ACE satellite for the period from 1998 to 2006.

Ionospheric response to the corotating interaction region-driven geomagnetic storm of October 2002 [PDF]
Unlike the geomagnetic storms produced by coronal mass ejections (CMEs), the storms generated by corotating interaction regions (CIRs) are not manifested by dramatic enhancements of the ring current. The CIR-driven storms are however capable of producing

Transequatorial magnetic flux loops on the sun: a possible new source of geomagnetic storms
Following the traditional way of expression, geomagnetic storms have been classified into three types; flare-type Sc storms, CH-type Sg storms, and DB-type Sc storms (Sc:sudden commencement;CH:coronal hole;g:gradual;DB:disparition brusque).We have ...

Auroral Oval Boundary Dynamics on the Nature of Geomagnetic Storm
During emergency events, we could significantly depend on the stable operation of radio communication, navigation, and radars. The ionosphere, especially its auroral regions, significantly influences radio systems, which is why scientists and engineers ...

Temporal and spatial variations in ionospheric electron density profiles over South Africa during strong magnetic storms [PDF]
Observations from the South African TrigNet global navigation satellite system (GNSS) and vertical total electron content (VTEC) data from the Jason-1 satellite were used to analyze the variations in ionospheric electron density profiles over South ...

RESPONSE OF BIOLOGICAL SYSTEMS TO GEOMAGNETIC STORMS
At present, influence of weak magnetic fields associated with solar and geomagnetic activity on biological systems is gaining more interest. Taking into account the accumulated data on the influence of geomagnetic storms on different biological levels ...

Plasmaspheric dynamics resulting from the hallowe'en 2003 geomagnetic storms [PDF]
Cross-phase-derived plasma mass density trends during the Hallowe'en 2003 geomagnetic storms are presented for 38° magnetic latitude 63° (1.61 ≤ L ≤ 5.10), using data from the SAMNET (Subauroral Magnetometer Network), BGS (British Geological Survey), and
