... The parameters presently supported by the QC0 application in place for UT1 include airmass, moon distance, fractional lunar illumination, and seeing, and correspond to the observation constraints available in the Phase II Preparation System. ...
... the exciting early scientific results are the first complete EUV allsky survey, the first EUV images of extended objects (e.g., the Moon, the Vela and Cygnus supernova remnants, and the JupiterIo plasma torus), and the first detection of helium on Mars ...
... Example 2: Locate the areas most frequently observed with an instrument in which the seeing is < 1 and the moon is below the horizon during the observation to produce very long exposures or perform time variation studies. ...
