SPAG-Monfragüe  Observatory SKY-CLOCK prediction:

Legend:

* C.W.F:  Clock work function: Generally speaking , it can be viewed as an indicator that if the cloud is likely to grow  ( BLUE= 0  probabilty...GREEN= 50% ...RED=100% or more)

* CLOUD COVER : Average total cloud cover (Transparent= Clear, .WWHITE = Overcast )

* SEEING : Astronomy seeing conditions (Deep Blue = < 0.5" ,Light Blue = 1"-1.5" ,WHITE = >2.5" )

* TRANSPARENCY : Integrated measure of extinction of sky objects. Unit is magnitude/airmass  ( Deep Blue= fine, < 0.5,Light Blue= medium 0.5 - 0.7 ,White = bad > 1 )

* LIFTED INDEX : Positive : atmosphete stable. Negative: atmosphere inestable . Temperature difference between an air parcel lifted adiabatically and the temperature enviroment  ( Deep Blue = >11 (Extremely stable.Thunderstorms unlikely); Green = 0-4 (mostly stable); Purple = < -7 ( very unstable.Thunderstorm probable)

* DARKNESS : Visual limiting magnitude at zenith ( White= -4 (very light) , Blue tones (3-5)moderately dark to dark , Black= 6 .Extremely dark )

*WIND : Average wind direction and speed at a height of 10m above the ground. Beaufort type table ( Deep Blue=calm,Light Blue=Light,Green=fresh., Yellow=moderate,Red=storm )

* TEMPERATURE . That on 2 meters above ground measured in Celsius(C) and Fahrenheit(F)

* R.HUMIDITY :Relative Humidity .Height above 2 meters. (Dark brown-brown < 40% , Yellow-light green50-70% , Deep Green > 70% )
