Panov) IWF/ÖAW5 Near-Earth Magnetotail Current Sheet Dipolarization front & flow bouncing:  Multiple fronts with different scales before flow-bouncing  Near-Earth current sheet disturbances are multi-scale in time and space (Nakamura et al., 2013) (Petrukovich et al., 2013) Oscillatory flow braking:  Observed profile recovered in MHD models  more in Poster (Panov)

August 2014: arrival of Rosetta at 67P/Churyumov-Gerasimenko  Plasma physics with RPC: Rosetta Plasma Consortium  Preparation study for detecting cometary plasma processes:  For different outgassing rates amplitude of water-group ion cyclotron (IC) waves in the undisturbed solar wind  Minimum level for detecting IC waves is examined using Pioneer 10 near Jupiter  Giotto flyby at 27P/Grigg–Skjellerup is used to estimate occurrence of IC waves IWF/ÖAW6 Cometary Plasma Physics  Cyclotron waves during Rosetta approach phase will provide indication of the outgassing rate of the comet (Volwerk et al., 2013) Lower limit from SW 0.1 nT amplitude

7.  Electron physics are main target in Magnetospheric Multi-Scale (MMS)  Magnetotail reconnection region with Cluster: highly structured, small normal component  New method developed to determine spin-axis offset from electron drift instrument (EDI) and applied to Cluster data  Magnetic field measurement accuracy of 0.1nT during entire orbit achieved Preparation for Electron-Scale Studies IWF/ÖAW7  Highly structured current sheet near X-line (reconnection region)  Accuracy of 0.1 nT at MMS  X-line structures can be determined within few 10s km resolution in magnetotail (Wang et al., 2014)
