Observing oscillations, flares and tornados on the sun

For six and a half days in July 2024, the balloon-borne solar observatory Sunrise III kept its gaze fixed on the sun.

The stratospheric flight, which stretched from the northernmost tip of Sweden to Canada's Northwest Territories, yielded a treasure trove of data exceeding 200 terabytes.

These observations are unique.

They provide insights—unprecedented in detail—into a layer of the sun approximately 2,000 kilometers thick and can continuously track its immense dynamics over several hours.
