Title : Sunrise: results from the second flight and plans for the third flight

 
Abstract : Sunrise is a balloon-borne solar observatory dedicated to the investigation of the physics of the magnetic field and its interaction with convective plasma flows and waves. The Sunrise observatory is designed for operation in the stratosphere (at heights up to 40 km) in order to avoid the image degradation due to turbulence in the Earth’s lower atmosphere and to gain access to the UV spectral range. The first science flights of Sunrise, in June 2009 and June 2013, led to many new results described in over 90 papers in refereed journals. This success has shown the huge potential of the Sunrise approach. Here some of the results obtained from the data gained during the second science flight will be presented. The recovery of the largely intact payload offers an opportunity for a third flight. Sunrise III will have greatly extended capabilities, in particular to measure weaker magnetic field over a greater range of heights (covering both photosphere and chromosphere). To this end, Sunrise III will carry two new instruments as well as upgrades of its present instruments.
