The 2004 June Bootid meteor shower
Bibliographic record
Abstract
The June Bootid meteor shower is known to show irregular activity. We report here the prediction and observations of the 2004 shower. The forecasts were independently performed by three different teams, who all concurred on a broad activity on June 23, though no estimate of the level was done prior to the event. Thanks to these predictions, observations around the world were conducted and gathered by the International Meteor Organization. The broad activity (full width at half-maximum ≃ 7 h) was observed, with a maximum occurring at 14:50 ± 60 min ut. The level of the shower reached a zenithal hourly rate (ZHR) of 30 ± 10, for a population index of r= 2.49 ± 0.15. Past showers are examined and new associations between the 1916 and 1998 showers and several trails from the early nineteenth century are made. An attempt to post-predict the values of the level of all these showers is discussed. New observations of comet 7P/Pons-Winnecke are needed when it returns in 2008.

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.
