Interplanetary shock parameters obtained from the in situ reconstruction from each spacecraft.
Spacecraft | r | Long | Lat | Shock arrival | Vshock | θBn | Vd/Vu | Bd/Bu | Bmax |
---|---|---|---|---|---|---|---|---|---|

(1) | (2) | (3) | (4) | (5) | (6) | (7) | (8) | (9) | (10) |
MESSENGER | 0.34 | 61 | 1 | 232.53 | 975 | 50 | − | 3.3 | 224.0 |
STEREO-B | 1.02 | 116 | −7 | 234.09 | 615 | 41 | 1.2 | 1.4 | 11.0 |
STEREO-A | 0.97 | 38 | −5 | 234.29 | 483 | 84 | 1.4 | 2.8 | 23.7 |
Notes. Column 1: observing spacecraft. Columns (2)–(4): radial distance, longitude, and latitude of spacecraft in heliographic inertial (HGI) coordinates (Burlaga 1984) at the time of shock arrival to STEREO-A (used as a reference). Columns (5)–(7): observed shock arrival time, shock speed (shock transit speed for MESSENGER), and angle between the shock normal and the upstream field. Columns (8) and (9): ratio between downstream (d) and upstream (u) solar wind speed and magnetic field strength. Column (10): maximum magnetic field strength observed within the ICME.
