Abstract
We report the first simultaneous ground and satellite conjugate observations of ELF/VLF waves associated with magnetospheric compression. On 23 December 2014, a receiver at subauroral latitudes at Athabasca (ATH), Canada (54.7N, 246.7E, L=4.3) observed an ELF/VLF wave burst centered at ~2.5 kHz. This emission showed discrete elements and lasted ~3 minutes starting at 11:17 UT (~2.4 MLT). RBSP-B, located nearly conjugate to ATH in the post-midnight sector (~3 3 MLT) observed a similar emission. This wave burst was observed a few minutes after an intense sudden impulse (SYM-H amplitude ~53 nT) caused by the enhancement of solar wind speed (~330 to ~420 km/s) and dynamic pressure (~2 to 6 nPa) during northward IMF. At 11:16 UT, RBSP-B also observed a separate hiss emission below 1.5 kHz that was not observed at ATH. We investigate the possible generation mechanisms of these waves and suggest that they differ for the hiss and discrete emissions and that their propagation to the ground is also different.

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
