This STEREO BEHIND (B) magnetic field 24-hour plot contains 1 minute averages of magnetometer data from the IMPACT instrument. The time in the plot title indicates the time a co-rotating structure at the BEHIND spacecraft will take to arrive at ACE. These data are directly comparable to the ACE MAG real-time plots. The magnetic field is displayed in the RTN coordinate system. On ACE, it is in GSM coordinates.
