In April and July 2014, the Sun emitted three jets of energetic
particles into space, that were quite exceptional: the particle flows
contained such high amounts of iron and helium-3, a rare variety of
helium, as have been observed only few times before. Since these
extraordinary events occurred on the backside of our star, they were not
discovered immediately. A group of researchers headed by the Max Planck
Institute for Solar System Research (MPS) and the Institute for
Astrophysics of the University of Göttingen (Germany) present a
comprehensive analysis now in the Astrophysical Journal.  [more]
