On October 20, 2022, at 10:00 we will have a seminar of the Department 
of Space Physics and Space Technology. David SIBECK, Chief Scientist, 
Heliophysics Science Division and Mission Scientist will discuss 
Remotely Sensing the Magnetosphere’s Boundaries. We are going to 
broadcast the talk. See the Zoom link below.

Outsiders contact Gabor FACSKO (facsko.gabor AT wigner.hu) related to entry 
to the campus.

Everyone is welcome to the seminar!

Üdvözlettel / Best regards,

“Remotely Sensing the Magnetosphere’s Boundaries”

Global magnetohydrodynamic models predict that plasma velocities vary 
almost linearly from 0 km s^−1  at the nose of the stationary 
magnetopause on the stagnation streamline to a limiting value of 0.25 
/V/_SW  for high solar wind Alfvénic Mach numbers at the nose of the bow 
shock, where /V/_SW  is the solar wind velocity. This paper presents a 
proof-of-concept study showing how two-point measurements of the plasma 
velocity in the subsolar magnetosheath can be used to determine 
gradients in the plasma velocity and consequently the steady-state or 
slowly moving locations of both the nose of the magnetopause and the 
nose of the bow shock. The results may be of use to those binning 
magnetosheath observations to develop empirical models, those testing 
models for magnetopause erosion or deposition in response to magnetic 
reconnection, and those determining the stand-off distance of the bow 
shock as a function of solar wind conditions.
