In extreme cases, these eruptions pose a safety risk to human health. Crew and passengers on air planes can be subject to solar radiation, astronauts in space receive unhealthy or even lethal doses. This is space weather. To study and to forecast space weather, we need state-of-the-art-technology to observe the Sun. One of our pearls is the PROBA3 duo-satellite, THE solar eclipse maker. This all is definitely worthwhile talking about it! STCE Solar Eclipse Conference 2018, Genk petra.vanlommel@observatoire.be http://www.vvs.be/agenda/solar-eclipse-conference-2018 OUTRTLK
