STEREO AHEAD 7-DAY MAGNETOMETER DATA

This STEREO AHEAD (A) magnetic field 7-day plot contains 5 minute averages of magnetometer data from the IMPACT instrument. The negative time in the plot title indicates the time a co-rotating structure at ACE will take to arrive at the AHEAD spacecraft. 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.
