Abstract

fetched live from OpenAlex

A merged data set from Canadian Auroral Network for the OPEN Program Unified Study (CANOPUS) and Magnetometers‐Ionospheric Radars‐All‐Sky Cameras Large Experiment (MIRACLE) magnetometer stations is used to study variations observed at widely separated locations. Three years of 10‐s data are analyzed using canonical correlation techniques to determine the temporal offset of similar fluctuations observed at pairs of sites. Nearly simultaneous (<2‐min delay) signatures are often found between sites separated by 12 hours magnetic local time, with no evidence of more slowly propagating events (> 10‐min delay). Correlated episodes occur more often (roughly 10% of the time) when sites are in the dawn/dusk sectors and less often (∼5%) for noon/midnight configurations.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
