Probable Sirius sighting in Montégut-en-Couserans

Summary

On 12 April 2008, two witnesses in Montégut-en-Couserans noticed a round, bright, multi-coloured light in the southwestern sky that stood out against the stars. They fetched binoculars and watched it for about ten minutes until it disappeared behind a hill. GEIPAN classified the case as B, suggesting it was probably Sirius, the brightest star in the night sky, which often surprises observers when seen low on the horizon on clear nights. The exact direction was not fully precise, leaving a slight margin of uncertainty.
