STEREO AHEAD 30-DAY MAG AND SOLAR WIND DATA

This STEREO AHEAD (A) magnetic field and solar wind 30-day plot contains 5 minute averages of magnetometer data from the IMPACT instrument and solar wind data from the PLASTIC 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 similar to the ACE SOLAR WIND: Magfield & Plasma real-time plots. The magnetic field is displayed in the RTN coordinate system. On ACE, it is in GSM coordinates.
