Scientific paper

The first results of a long-term seeing measurement program at the University of Hawaii 2.2-m telescope on Mauna Kea are presented. During a one-year period from August 10, 1985 to August 13, 1986, the median seeing was 0.88 arcsec for a wavelength of 0.7 micron. The weak correlations of the UH 2.2-m seeing with the dome thermal environment and with the CFHT 3.6-m seeing indicate that the UH 2.2-m dome and the atmosphere make comparable contributions to the total seeing. There is no significant dependence on wavelength wind direction, or time of year. Increasing wind speed, however, does contribute negatively to the seeing. These data will be used as a baseline against which planned improvements to the dome thermal balance of the UH 2.2-m telescope will be assessed.
