All-Sky Imager

Owner

Finnish Meteorological Institute (FMI)


Scientific objectives
The all-sky camera will be used to continuously monitor the high-latitude auroral forms. Similar cameras will be installed in northern Finland to monitor the auroral zone. Data from these cameras together with magnetometer data from IMAGE magnetometer network will be used to study the auroral morphology, precipitation patterns, and ionospheric currents during both magnetically disturbed and quiet times. Especially, the Svalbard camera will be used to monitor the polar arcs that occur during northward and dayside auroral forms related to the cusp.
