icam (Interhemispheric Conjugate Aurora Monitoring) is a unique aurora monitoring project designed to build up a large database of systematic interhemispheric conjugate optical observations at the Iceland-Syowa pair.
At Syowa Station in Antarctica and two stations (Tjörnes and Húsafell) in Iceland, the automatic optical instrument equipped with a simple white-light all-sky CCD camera (Watec, WAT-120N+) has been operating. At present, the geomagnetic conjugate point of Syowa Station deduced from the IGRF model is closer to Tjörnes in northeastern Iceland than Húsafell.
The icam database would provide a useful basis for examining interhemispheric conjugate auroral phenomena.
