29P/Schwassmann-Wachmann 1 light curves

Stellar occultations enables detailed study of cometary nuclei typically hidden by their coma. Observing the star's light passing through the coma helps infer dust's optical depth near the nucleus and determine dust opacity detection limits. 29P/Schwassmann-Wachmann 1, a Centaur with a diameter of approximately 60km, lie s in a region transitioning from Centaurs to Jupiter-Family comets.

Our study presents the first-ever occultation by 29P, refining its orbit and predicting future occultations more precisely. We identified features around 1700km from the nucleus in the sky plane for which upper limits on apparent opacity and equivalent width were determined. Gradual dimming within 23km of the nucleus during ingress only is interpreted as a localised dust cloud above the surface, with an optical depth of approximately tau=0.18.
