Green Flash of Sirius

The green flash of the brightest star in the sky.

Around mid-May, Sirius reaches the western horizon and sets in the twilight lights.

This is the best time to try to admire its sunset and the play of colours it creates with the atmosphere in a still bright context.

Here it is taken through a 12" dobsonian Meade telescope, as it sets, less than 4° from the horizon, next to a pine tree more than 1.6km away from the observation point.

The video taken with a Huawei p30 Pro smartphone. The collage is made of some frames of that video.
