Prolonged Magnetopause Recovery From the Impact of a Strong Stream Interaction Region
Bibliographic record
Abstract
Abstract High solar wind dynamic pressure, particularly during stream interaction regions (SIRs), can strongly compress the Earth's magnetosphere, posing a risk to space‐based technologies critical to modern society. This study investigates the response of the low‐latitude magnetopause to an extreme SIR on 14 March 2016, using in situ observations. The magnetopause was compressed inward to near geosynchronous orbit and remained compressed for several hours after the SIR's passage, revealing an unusually prolonged recovery phase. We present three lines of analyses: (a) multi‐spacecraft observations of magnetopause crossings; (b) magnetic pressure measurements inside the magnetopause; and (c) ground‐based records of low‐latitude geomagnetic field perturbations. The extended recovery challenges the conventional view that the magnetosphere rebounds within minutes after solar wind compression. These findings highlight the complexity of magnetospheric dynamics under extreme conditions and the need for further investigation into these regions, in order to improve space weather forecasts and protect critical technologies.

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.
