A systematic analysis of the thermospheric density response to changes in the interplanetary magnetic field (IMF) sector polarity is carried out. For this purpose we use a high‐latitude southern thermospheric total mass density near 400 km altitude, derived from the high‐accuracy accelerometer on bo...
