Pioneer 11 HVM Hourly Average Interplanetary Magnetic Field


Availability: At NSSDC, Ready for Electronic Access

Time span: 1973-04-06 to 1992-01-01


The Helium Vector Magnetometer (HVM) measurements of interplanetary magnetic fields are averaged at one-hour intervals with respect to Spacecraft Event Time (UT). Data set parameters include the three orthogonal components of the magnetic field in RTN coordinates, where R is in the sun-s/c direction, T is the cross product of the solar rotation axis and R, and N is the cross product of R and T. The hourly field magnitude, averaged over scalar magnitudes at higher time resolution, is also provided. All field values are in nanotelsa.
