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 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 (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.

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 (front and back) Gibbes provides a diagram of the phases of the eclipse and the circle of the Earth's shadow when the moon enters the shadow, eclipse begins, middle of eclipse, end of eclipse and the moon leaving the shadow. On the back of the page Gibbes provides the elements for constructing the diagram. Those elements are hourly motion, declination, hourly motion in declination, horizontal parallax and semidiameter. Gibbes also provides the time of the aforementioned phases.
