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. The diagram shows the central path for the moon during the eclipse.
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 Gibbes provides his calculations for the result times.
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 (front and back) Gibbes provides a diagram and the phases and calculations of a total lunar eclipse including the moon entering the Earth's shadow, total eclipse, middle of eclipse, end of eclipse and the moon leaving the Earth's shadow. On the back of the diagram Gibbes denotes that this chart was made for his classes at the College of Charleston in Charleston, S.C.
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.
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 Gibbes provides a transit of planet Mercury across the sun. Gibbes includes the beginning, middle and end of the transit along with the parallel of declination, limb of the sun and relative path of Mercury.
In this astronomical chart (front and back) on the front of the page Gibbes provides a diagram and the elements for constructing the diagram. Also included are his calculations of the partial lunar eclipse including the hourly motion, declination, hourly motion in declination, horizontal parallax, and semidiameter. Gibbes also provides the results of the eclipse (phases of the eclipse: beginning, middle, end and duration). On the back of the page Gibbes provides the calculations from the quantities given on the front page to calculate logarithms, the auxiliary quantities, and relative orbit described by the moon in one hour of time.
