Project description:
The ITACA² observatories, ITACA-NAL and ITACA-DNB, are located in Ny-Ålesund (Lat = 78° 55’N, Long = 11° 56’E, Spitsbergen, Svalbard archipelago) and Daneborg (Lat = 74° 18’N, Long = 20° 13’W , North-East Greenland), respectively. They are equipped with the standard all-sky cameras used in the Miracle network, which automatically collect all-sky images with three interference filters (BW 2.0nm), wavelengths 557.7nm (green), 630.0 nm (red) and 427.8 nm (blue). ITACA² field-of-view covers a zone up to about 20° x 130° (Lat x Long), centred at about 76° magnetic latitude, when observing high-altitude (~400km) red-dominated dayside “cusp” auroras. The wide area monitored by ITACA² extends the ground-based observations of the geomagnetic cusp/LLBL regions, and enhances the capability of conjugate studies with ionospheric radar (SuperDARN), magnetometer chains and satellite data. In this context ITACA² can monitor the magnetic reconnection pattern and dynamics at the dayside magnetopause between the Earth’s magnetosphere and the interplanetary magnetic field (IMF). ITACA² can also monitor the high-latitude night-time auroras, which occur during the poleward expansions of the auroral oval caused by intense geomagnetic substorms, and also the auroral intensifications linked to boundary phenomena acting on the edge between open and closed geomagnetic field lines. Thanks to an agreement between INAF-IAPS and FMI-Space, ITACA² constitutes the Italian contribution to the MIRACLE international network.
