Site Study of Dome C (Tomasi et al.) Sun @ 10°: 750 max!
Summer Seeing Summary Excellent seeing better than 1 arcsec for 2000 hours/ year (h > 32 m); AO-MCAO 0.8 arcsec (r 0 > 12 cm) for more than 1700 hours/year (more than twice the possibilities of any other solar site): HAR observations definite advantage Free atmosphere seeing limited, elevation corrected, of 0.5" (h > 32 m), during a minimum of 4 hours around 5pm every clear available day for coronal observations: the "afternoon" advantage of the summer season at Dome C 0.5", r 0 = 20 cm @ 0.5 µm ("small" 700 mm telescopes are almost phased at 1 µm when seeing = 0.3") - IR (corona) phased at 3 µm.
