Summary
Description
This data file was generated as part of the International Magnetospheric Study (IMS). The file consists of values of the geomagnetic components D, H, X, Y, Z, and R averaged from 10-second instantaneous measurements. The 1-minute average values are computed at the Space Environment Center (SEC) in Boulder, Colorado, on the SELDADS computer system. The 10-second values are collected digitally in real time at the ground observatories and relayed to SEC via the SMS_GOES satellite and Wallops Island, Virginia, ground station. Twenty-six geomagnetic observatories provide data.
