Goal

Report on results of Task 4.2 Solar wind – magnetosphere coupling and the terrestrial impact by comparing solar wind observations and magnetospheric energetic particles

Progress so far

At KFKI RMKI intervals were searched for when magnetopause and/or bow shock crossings were observed by the Cluster spacecraft during very large solar wind dynamic pressure (>10 nPa). Interplanetary parameters were taken from the OMNI dataset. A few selected intervals correspond to the CME events listed by the working group.

At KU Leuven selected conditions for realistic modeling of reconnection regions both in the dayside and in the tail were investigated by implicit particle-in-cell code Parsek in collaboration with the teams of NASA MMS mission. The focus has been primarily in elucidating the role of electron holes and their induced turbulence on the reconnection. Access to the SPENVIS online system is acquired and its use is studied, in order to utilize it for investigating the effect of radiation on satellites.

UOulu is working to intercalibrate the energetic particle data from the several low-altitude NOAA/POES satellites. These particle data will also be used in a semi-empirical model (under construction) for the corrected Dst index to separate the effect of different current systems.

List of the people working on this deliverable: MTA-KFKI-RMKI: Mariella Tatrallyay, Zoltan Nemeth; DTU: Susanne Vennerstrom; UOulu: Kalevi Juhani Mursula, Timo Asikainen; KU Leuven: Marina Skender;
