Additional information to your astronomical seeing prediction:

  • Values may not reflect precisely reality
  • For good seeing conditions look for dark blue colors in the cloud cover and green values in the Seeing Indices and Jet Stream
  • The estimated seeing indexes (1 & 2) range from 1 (poor) to 5 (excellent) seeing conditions. This value is computed based on the integration of turbulent layers in the atmosphere.
  • Estimation of seeing in arcseconds. This is a test prediction under development, uncalibrated for the time being.
  • Cloud cover ranges from dark blue (0% cover) to white (100% cover). Fog or very low cloud is not shown here (see pictocast for fog)
  • High jetstream speeds (>35m/s) usually correspond to bad seeing, as well as very low speeds (<5m/s). Color gives a hint.
  • Bad Layers have a Temperature Gradient > 0.5K/100m. The actual gradient is shown K/100m. The top and bottom height of the Bad layers is indicated by Bad Layers bot/top
  • Visible planets and coordinates also considering temperature profiles of the atmosphere. The following planets are available: MVMJSUNP => Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.
  • If you move your courser over the visible planets column, hourly coordinates for each planet will appear: Azimuth (Az) from north with altitude in degree (Alt) onto horizon, right ascension (RA) and declination (DEC). We may consider adding 10 minutes coordinates and additional objects on request.
