Akebono/Suprathermal Mass Spectrometer observations of low‐energy ion outflow: Dependence on magnetic activity and solar wind conditions
Bibliographic record
Abstract
We present observations by the Suprathermal Mass Spectrometer (SMS) on Akebono (EXOS‐D) of ion outflow in the energy range from <1 to ∼70 eV. These observations cover a unique region of phase space and present an opportunity to “tie together” observations from disparate satellites. Variation of the total hemispheric O + and H + outflow rates with solar radio flux (monitored by the Penticton F 10.7 index), with geomagnetic activity (monitored by the Kp index), and with solar wind parameters is discussed. Comparisons of F 10.7 and Kp trends to results from Polar and Dynamics Explorer‐1 (DE‐1) lead us to conclude that flows of H + in this low energy range are entirely sufficient to account for higher‐energy flows at higher altitudes. On the other hand, we infer a substantial amount of O + at energies above 70 eV. Both H + and O + outflow rates in this range exhibit a strong correlation with the solar wind kinetic pressure, the solar wind electric field, and the variability in the interplanetary magnetic field (IMF) in the hour preceding. While these factors are also associated with increased geomagnetic activity ( Kp ), a separate, Kp ‐independent effect is also found, showing a correlation of ion outflow with solar wind density and an anticorrelation with solar wind velocity.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
