Abstract
The authors proposed a method for modeling geomagnetic field variations based on the construction of wavelet packets. The article presents the results of modeling and data analysis during periods of increased solar activity and magnetic storms. We used onesecond geomagnetic data from the stations of the polar zone «Abisko» (Sweden, 68°21.7’N 18°43.4’E) and «Ministik Lake» (Canada, 53°21.0’N 112°59.0’W). The paper proposes an algorithm for identifying geomagnetic pulsations (fluctuations in the frequency band from thousandths to several Hz), which are characterized by a quasiperiodic structure. On the basis of modeling, short-period geomagnetic disturbances of moderate and weak intensity were detected, which precede magnetic storms and characterize the occurrence of oscillatory processes in the Earth’s magnetosphere against the background of an increase in heliospheric activity. The paper proposes computational solutions for the detection and estimation of parameters of geomagnetic disturbances for the automation of the method.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
