Abstract

fetched live from OpenAlex

The black drop effect during the 2004 transit of Venus against the Sun has been observed and photographed by amateur astronomers in Montreal (Canada). It is shown in this report that the black drop can be explained by the contact then the disappearance of the halos surrounding Venus and the Sun at contact point. The black drop thus appears to be a real part of the disk of Venus and not an illusion of optical perception. RESUME. Le phenomene de la goutte noire pendant le transit de Venus devant le Soleil a ete observe et photographie par des astronomes amateurs a Montreal (Canada). On a pu ainsi expliquer la formation de la goutte noire par le contact puis la disparition des halos autour de Venus et du Soleil au point de contact. La goutte noire apparait ainsi comme etant une partie reelle du disque de Venus et non pas une illusion de perception optique.

Full frame distilled prediction

Teacher imitation

Not 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.
