Sunrise

Analyzing the high spatial resolution solar Ca II H and K emission data obtained by the SUNRISE mission and building a model of other stars more active than the Sun more

The magnetic field in the solar atmosphere exceeds the geomagnetic field strength by four orders of magnitude. It greatly influences the processes of energy transport within the solar atmosphere, and dominates the morphology of the solar chromosphere and corona. Kinetic energy from convective motions in the Sun can be efficiently stored in magnetic fields and subsequently released - to heat the solar corona to several million degrees or to blast off coronal mass ejections. more

As photos from the landing site show, Sunrise III is in good shape after its stratospheric research flight. First observational data look promising. more

The balloon-borne solar observatory is now flying westwards along the Arctic Circle. From the stratosphere, it has an incomparable view of the Sun. more

Stratospheric winds and weather conditions on the ground will now decide when the balloon-borne solar observatory can take off on its research flight. more
