Additional information to your astronomy seeing prediction:

  • Look for dark blue colors in the cloud cover and green values in the seeing indexes and jet stream for good seeing conditions.
  • The estimated seeing indexes (1 & 2) range from 1 (poor) to 5 (excellent) seeing conditions. These values are computed based on the integration of turbulent layers in the atmosphere.
  • Cloud cover ranges from dark blue (0%) to white (100%). Fog or very low clouds are not shown here (see pictocast for fog).
  • High jetstream speeds (>20m/s) usually correspond to bad seeing.
  • Bad layers have a temperature gradient of more than 0.5K/100m. The top and bottom heights of the bad layers are indicated.
  • LMVMJSUNP => Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.
  • Move your cursor over the celestial bodies column to see coordinates for each celestial body: Azimuth (Az), altitude (Alt), right ascension (RA) and declination (DEC).
