Geomagnetic Fields and Total Electron Content Variations at Eagle Station During Solar Storms of Solar Cycle 24
Bibliographic record
Abstract
In this work, we analyzed variations in the Earth’s magnetic field components (D, H, and Z), interplanetary magnetic field (IMF-Bz), interplanetary electric field (IEF-Ey), and GPS-derived total electron content (TEC) during three solar storms observed over Eagle Station (64.7860°N, 141.1999°W) in Canada during Solar Cycle 24. The selected events include a moderate storm (25–27 October 2011), an intense storm (15–19 March, 2015), and a weak storm (6–10 May, 2018). The results indicate that solar storms caused notable disturbances in all components of the geomagnetic field, with the D, H, and Z components showing marked decreases during storm periods. These disturbances were accompanied by a corresponding increase in TEC. Additionally, the degree of geomagnetic variation was closely linked to the intensity of geomagnetic storms.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
