1. 1. Determining the alignment of Solar Orbiter instruments STIX and EUI during solar flares

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Författare :Sofia Tynelius; [2022]
   Nyckelord :Solar flares; the Sun; STIX; EUI; alignment; pointing;

   Sammanfattning : Solar Orbiter is a mission launched in 2020 that will take images closer than ever of the Sun. It has ten instruments on board, including The Spectrometer/Telescope for Imaging X-rays (STIX) and The Extreme Ultraviolet Imager (EUI). LÄS MER

3. 2. Assessment of weather conditions for ALMA observations of the Sun

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Daniel Jakobsson; [2020]
   Nyckelord :Atacama Large Millimeter Array; ALMA; Solar observation;

   Sammanfattning : The closest star to Earth is the Sun. The difference between our Sun and other stars is that the dynamics are observable with telescopes. A complex and strange part of our Sun is the chromosphere which is a part of the solar atmosphere. LÄS MER

4. 3. Inference of chromospheric magnetic fields with the Ca II 8542 line
