The sound of the solar wind at Venus

The variability of the total magnetic field during BepiColombo’s second Venus flyby as measured by the Mercury Planetary Orbiter’s Magnetometer (OB sensor). The timeframe covers 12:00 to 14:30 UTC on 10 August 2021, including the closest approach at 13:51 UTC. The data is not yet cleaned from high pitch spacecraft disturbances, but the lower-pitch wind-like sounds allow a rare glimpse into the solar wind interaction with a planetary atmosphere. For example, activity is detected on the approach to Venus and with the magnetic field ’pile-up’ around closest approach. A more intense wind-like noise represents the turbulent magnetosheath region, before the sudden transition at the bow shock into the very calm solar wind.
