The Gattini network consists of three cameras located at the high-altitude Antarctic sites Dome C, Dome A, and South Pole. These star transit cameras monitor wide areas of the southern sky, taking an image every five to 15 minutes throughout the entire Antarctic winter season. The network has been in operation since the 2006 austral winter season, collecting data sets totalling in excess of three Terabytes. The project's data reduction and analysis effort will focus on two distinct areas: (1) Obtaining photometric light curves of the brightest and most interesting long-period variable stars in the southern sky, which have known parallaxes and other parameters and are unique stars with no counterparts in the Kepler spacecraft field; and (2) Producing astronomical site testing results that are critical for validating high-altitude Antarctic sites to allow planning of future large astronomical facilities.
Field Season Overview:
The Gattini-SP instrument was installed in January 2011 and has been operational since February 2011. Project researchers control the camera from their home institutions. This year, no project participants will deploy. Contract staff members will monitor the system and perform maintenance as needed.
