SUMMARY:Solar-terrestrial relations – combined remote sensing and in-situ
  data
DESCRIPTION:Solar-terrestrial relations – combined remote sensing and in-
 situ data\nProf. Manuela Temmer\n\nThe Sun is an active star that influenc
 es the Earth as well as the entire solar system. Most dynamic phenomena on
  the Sun are observed as coronal mass ejections (CMEs) and flares. CMEs pr
 esent massive clouds of magnetized plasma having speeds up to a few thousa
 nd km/s, that may propagate over Sun-Earth distance within less than a day
  and may cause strong geomagnetic disturbances at Earth (Space Weather). A
 s CMEs are optically thin, using remote sensing data measurements of intri
 nsic properties such as speed, width, propagation direction, density etc. 
 are severely affected by projection effects. By combining image data with 
 in-situ measurements, valuable information is provided enabling CME 3D ana
 lyzes, and with that facilitate a better quantification of the uncertainti
 es in the observational measurements that are used to feed CME propagation
  models. With that, a much better understanding of CMEs as they propagate 
 in interplanetary space could be gained.The talk will cover the physisc ab
 out CME-flare phenomena, the interplanetary propagation behavior of CMEs r
 elated to the background solar wind, and Space Weather forecasting.\nZoom
