Method Details

compute

public static MoonPosition.Parameters compute()

Starts the computation of MoonPosition.

Returns:

MoonPosition.Parameters to set.

getAltitude

public double getAltitude()

Moon altitude above the horizon, in degrees.

0.0 means the moon's center is at the horizon, 90.0 at the zenith (straight over your head). Atmospheric refraction is taken into account.

See Also:

• getTrueAltitude()

getTrueAltitude

public double getTrueAltitude()

The true moon altitude above the horizon, in degrees.

0.0 means the moon's center is at the horizon, 90.0 at the zenith (straight over your head).

Since:

3.8

See Also:

• getAltitude()

getAzimuth

public double getAzimuth()

Moon azimuth, in degrees, north-based.

This is the direction along the horizon, measured from north to east. For example, 0.0 means north, 135.0 means southeast, 270.0 means west.

getDistance

public double getDistance()

Distance to the moon in kilometers.

getParallacticAngle

public double getParallacticAngle()

Parallactic angle of the moon, in degrees.

toString

public String toString()

Overrides:
