Local weather elk grove ca5/23/2023 ![]() Large globulars and planets can be observed in poorĪ forecast color of white formally means that CMC didn't compute the transparency forecast because the cloud cover was over 30%. However, open clustersĪnd planetary nebulae are quite observable in below average transparency. It is somewhat independant of the cloud cover forecast in that there can be isolated clouds in a transparent air mass, and poor transparency can occurĪbove average transparency is necessary for good observation of low contrast objects like galaxies and nebulae. It's calculated from the total amount of water vapor in theĪir. The total transparency of the atmosphere from ground to space. Here 'transparency' means just what astronomers mean The line, labeled Transparency, forecasts the transparency of the air.
