In this work we revisit an event observed by Mars Atmosphere and Volatile Evolution MissioN in the solar wind where the interplanetary magnetic field (IMF) rotates around the Mars-Sun axis during similar to 6 min. Based on a time-dependent LATMOS Hybrid Simulation, we determine recovery timescales of the dayside Martian magnetosphere normalized by the IMF variability timescale. Particularly, we find that such recovery timescales range between 8 s and 11 min for an similar to 90 degrees IMF rotation that lasted 50 s (observed as part of the 6-min time interval), depending on the considered magnetospheric region. We also find that the O+ plume recovery timescales range between 40 and 120 s, taking greater values for further downstream distances (at least up to 1R(M) downstream from the terminator plane). This range is on the order of the magnetosheath O+ gyroperiod, showing the kinetic nature of the plume recovery process.
