In this astronomical chart Gibbes provides a diagram and the elements for constructing the diagram. Those elements are hourly motion, declination, hourly motion in declination, horizontal parallax and semidiameter. Gibbes also provides the result times of the eclipse including the beginning, total, opposition, middle, end of total, general and duration of eclipse.
In this astronomical chart Gibbes provides a diagram, its calculations and results (phases of the eclipse: beginning, middle end and duration), and the mathematical calculations for a total eclipse in relation to the elements of the eclipse. Those elements are time (Greenwich Mean Time), hourly motion, hourly motion in declination, relative motion, declination, semidiameter and horizontal parallex.
In this astronomical chart Gibbes provides a diagram and the elements for constructing the diagram. Those elements are hourly motion, declination, hourly motion in declination, horizontal parallax and semidiameter.
In this astronomical chart (front and back) Gibbes provides on the front page a diagram and the elements for constructing the diagram. Those elements are hourly motion, declination, hourly motion in declination, horizontal parallax and semidiameter. Gibbes also provides the result times of the eclipse including the beginning, total, opposition, middle, end of total, general and duration of eclipse. On the back of the page Gibes provides the calculations from the quantities given on the front page to calculate the auxilary quantities and times relative orbit described by the moon in one hour of time.
In this astronomical chart Gibbes provides a diagram, its calculations and results (phases of the eclipse: beginning, middle, end and duration), and the mathematical calculations for an annular partial eclipse of the sun in relation to the elements of the eclipse. Those elements are time, hourly motion, declination, hourly motion in declination and horizontal parallax.
