Sunrise is a balloon-borne astronomical observatory designed to observe the Sun's photosphere and chromosphere. It carries a 1-metre solar telescope that redirects infrared, visible, and ultraviolet radiation from the Sun to a suite of scientific instruments. Sunrise is managed by the Max Planck Institute for Solar System Research.

Sunrise completed three successful science flights between 2009 and 2024. Sunrise I and II, flown in June 2009 and June 2013, respectively, both carried an imager and magnetograph. Sunrise III, flown in July 2024, carried updated instrumentation including two slit-based spectropolarimeters and a new magnetograph. All three flights were launched from the Esrange Space Center near Kiruna, Sweden and around the Northern-Hemisphere summer solstice when the polar day allowed for continuous observation of the Sun.

The first science flight of Sunrise yielded high-quality data that reveal the structure, dynamics and evolution of solar convection, oscillations and magnetic fields at a resolution of around 100 km in the quiet Sun.
