We are examining magnetic field fluctuations in and around interplanetary shocks observed by the DSCOVR spacecraft. The DSCOVR spacecraft, launched in February 2015 and currently in an orbit about L1, provides very high cadence measurements of the magnetic field (50 Hz) and ion velocity distribution functions (1 Hz). Observations suggest the fluctuations near the shock ramps are whistler precursors. The properties of both the precursor waves and the shock ramp structure are compared to the shock geometry and strength. The observations are compared with the observations by the Wind spacecraft, also in an orbit about L1.
