A non-magnetic pillar for observation of geomagnetic field was installed at Seal Rock, East Antarctica in January 1987 by the 28th Japanese Antarctic Research Expedition. A G.S.I. (second-order) precise magnetometer was set on the pillar, and absolute measurements of the geomagnetic field were made 7 times during 19 September-18 December, 1987. The averaged values of the observed declination angle, inclination angle and the total magnetic intensity are -36°19.2' (westward), -63°53.3' (upward) and 43073nT, respectively. These observed values are consistent with the theoretical values calculated by the IGRF (1985) model.
