Geomagnetic Variation Data - 1-Minute Remote Geophysical Observatory Network (RGON)
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.
