Description
The Samoa Observatory is located on the northeastern tip of Tutuila island, American Samoa, on a ridge overlooking the South Pacific Ocean. Established in 1974 on a 26.7 acre site, the observatory is the fourth of the ESRL/GMD Baseline Observatories. Since it's construction, the Samoa Observatory has survived two major hurricanes with only minor damage. A staff of 3 operates the year around facility commuting to work. This Observatory has the distinction of obtaining 30% of its daytime power from solar panels.
