Paper Abstract

The average seeing at the University of Hawaii 2.2 m telescope from 10 August 1985 to 9 January 1986 was 0.95 ± 0.02 arcsec full width at half-maximum at a wavelength of 0.70 pm. We believe that the dome makes substantial contributions to this average because the see-ing degrades with increasing temperature difference between a point near the primary mirror and the outside air. There is no significant dependence on wavelength (over the range 0.63-0.82 μm), wind direction, or time (over the interval covered to date). The data reported in this paper are the baseline against which we will assess the results of a long-term program of dome thermal balance improvements.
