    Dear Team,

    Again thank you for adding illustration as requested, It may be better if there any option like a slider to provide average elevation only when azimuth is zero. That is pure Elevation when sun is at it peak of any solar cycle.

    In current UI to approximately track it using the time bar of the day is very hard and need to take multiple iterations to be confident about elevation sun when it is at the peek.

    And similarly the azimuth of with elevation is zero i.e. azimuth during sunset and sunrise can help to know solar swing and design of tracking system.

    Dear team,

    Thanks vary much well I have problem in understanding this angels based on the nonmature of this angels. most of the time it create confusion and I have to scribble again to build the confidence about the data.

    I hope there is no mistake in data but just for quick reference if you provide illustration of angle you mention above.

    something like this (

    Just to build confidence that we are on same page about the angles we are taking about.

    Purpose of use
    Attempting to to determine for how many hours/day at any given time of year the sun will be at or greater than 30 degrees altitude for a specific location
    While this data is interesting, it isn''t precisely what I was looking for. Does anyone know hoe I can better find the information I am looking for?

    Purpose of use
    Trying to understand relationship of equinoxes and solstices to places within the tropics where the sun''s altitude should reach (and exceed) 90deg
    I don''t seem to be able to discover any days of the year where the sun''s altitude is 90deg for my place of observation in St.Helena, South Atlantic Ocean (15.9deg South). Can this be right?
    from Keisan
    The maximum value of the sun's altitude is 90deg. (Sun's Altitude <= 90deg)
    The sun's altitude takes almost 90deg in St.Helena in November 2018.
