Solar wind observations from BepiColombo MPO-MAG and BERM during 9-11 Oct 2021

This dataset contains unreleased data from the BepiColombo mission for the period 2021-10-09 to 2021-10-11 during the cruise phase to Mercury. In particular, it contains magnetic field observations from the MPO-MAG instrument (Heyner et al. 2021), and energetic particles from the BERM instrument (Pinto et al. 2022).

****************IMPORTANT NOTE****************

These data have not been released yet to the Planetary Science Archive (PSA). As consequence, they may still suffer some changes due to future calibrations before they are released to the PSA.

Therefore, we strongly encourage all the users to contact the following people before using this dataset.

- Dr Beatriz Sánchez-Cano, University of Leicester, BepiColombo Guest Investigator, bscmdr1@leicester.ac.uk

- Dr Daniel Heyner, TU Braunschweig, Principal Investigator of MPO-MAG, d.heyner@tu-bs.de

- Dr Richard Moissl, European Space Agency, Principal Investigator of BERM, richard.moissl@esa.int

File descriptions:

- MPO-MAG file, named: “Bepi_MAG_RTN_282_284_2021_5min_avg.dat”

It contains derived data from the outbound sensor averaged every 5 minutes. The file has 7 columns with the following information:

1- Initial time (days of October 2021)

2- End time (days of October 2021)

3- Radial component of the magnetic field (B_R) in nT and in RTN coordinates.

4- Tangential component of the magnetic field (B_T) in nT and in RTN coordinates.

5- Normal component of the magnetic field (B_N) in nT and in RTN coordinates.

6- Cone angle (theta) of the magnetic field in degrees.

7- Clock angle (phi) of the magnetic field in degrees.

- BERM file, named: “BERM_OCT_2021.txt”

It contains uncalibrated “raw” counts. A calibration is currently being performed. All channel units are "counts". Each column has the following information:

1- 6: UT Time (DD MM YYYY HH MM SS)
