The development and performance of a very low power consumption unmanned geophysical observatory are described. The observatory, now in operation south of Casey, Antarctica, includes instrumentation for the study of auroral morphology, ionospheric opacity, geomagnetism, and micrometeorology; average power consumption is 0.75 watts and operation to ambient temperatures of -85℃ is feasible. Reliable performance for periods up to one year has been achieved.
