Response of ionospheric convection to sharp southward IMF turnings inferred from magnetometer and radar data
Bibliographic record
Abstract
Reconfiguration of the convection pattern associated with a sudden transition in the north/south component of the IMF from stable positive to stable negative values is investigated for two events using both magnetometer and SuperDARN data. The IMF transition impinges upon the magnetosphere near the 10 MLT sector; perturbations are clearly seen on the dayside at the time of onset and on the nightside with a ∼10 min delay from onset. This implies a dayside‐to‐nightside progression of the ionospheric response observed in the magnetic perturbations and SuperDARN velocities, contrary to the globally simultaneous response reported in the literature for a number of other events. The foci of the dawnside convection cells are shown to shift from near midnight toward the dayside, reaching a final location between 06 MLT and 08 MLT within 14–18 min of onset. The location of the duskside convection cell remains in the early afternoon sector both prior to and after the transition for both events. Once the convection foci reach a final location, the overall convection pattern enhances.

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.
