How to read the forecast

  • Dark blue around clouds = low cover; green seeing pills and jet stream numbers mean stable skies.
  • Seeing indexes 1 & 2 range from 1 (poor) to 5 (excellent) based on atmospheric turbulence.
  • Cloud columns reflect 0% (deep navy) to 100% (white); fog/low clouds are omitted.
  • Jet stream speeds above ~20 m/s often degrade seeing quality.
  • Bad layers show where temperature gradients exceed 0.5 K/100 m; both the base and top heights help you spot turbulence.
  • Celestial acronyms (LMVMJSUNP) = Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto.
  • Hover over the celestial column to see Az/Alt/RA/Dec for the listed bodies.
