- Title
STATUS OF VISTA, AND PUBLIC SURVEYS.

- Abstract
VISTA is the new 4-metre wide-field survey telescope now nearing completion at ESO's Paranal Observatory. It has a single instrument, a very large near-infrared camera with a 1.65 degree diameter field, 67 Mpixels and 0.6 deg² active detector coverage. Most of VISTA's observing time will be used by six Public Surveys recently selected by ESO. Comparing to possible future surveys from Dome C, a 2.4 m class telescope at Dome C would give slightly better sensitivity than VISTA at Y, J,H bands, but would require an unrealistic number of near-IR detectors to match VISTA's field of view. In the Kdark and visible bands the comparison is much more favourable to Dome C, so a good strategy for Dome C surveys is to emphasise complementarity by concentrating on the Kdark band, and i-band weak lensing surveys.
