Scope and Contents

Calculations, in pencil, relating to astronomical observations made by Tycho Brahe and Johannes Hevelius.

Scope and Contents An untitled book of lunar and planetary calculations and tables, with some work on the Sun, 178 folios. There is a note about the receipt of a portrait of Tycho Brahe (9r), Latin quotations (178v), other personal notes (especially inside the back cover), and an index to the calculations (177v-178r). The writing is mostly in Flamsteed's hand, and contains parts where the handwriting is illegible. There are dates from 11 June 1703 to September 1719, but the volume may include some work...

Scope and Contents

An investigation into the latitude of Uranibourg from the meridian altitudes of stars observed by Tycho Brahe and a comparison of his observed meridian altitudes of the Sun with Le Verrier's solar tables together with an investigation into the place of the ecliptic, 1582-1590. The volume also contains an investigation into Hevelius's observations of the Sun's meridian altitude in 1679.

Scope and Contents An undated collection of observations, mostly planetary, made with the sextant between July 1676 and September 1689, with an additional synopsis for each planet covering 1582-1714; in Flamsteed's and other hands; 186 folios. The volume includes notes on comets of 1682-1683 (104v-108r); a copy of Tycho's star catalogue (109r-119r); a copy of Lawrence Rooke's observations of Jupiter's satellites (124r-127v), with Flamsteed's own for 1677-1689 (136v-144v); sunspots, 1676-1684 (155v-161v); and a...

Scope and Contents A copy of Porter's script for 'The Night Sky in October' on cycles in nature and astronomy; Jupiter in Gemini below Castor and Pollux, its retrograde motion and opposition, and the three-fold conjunction with Uranus; finding Uranus in the night sky, the achievement of William Herschel, and the close conjunction of Jupiter and Uranus on 10 May 1955; Mercury, Venus and Saturn not visible, and the rising and setting of Mars at the time of a summer opposition; ancient astronomy and epicycles,...

Scope and Contents Two copies of Porter's script for 'The Night Sky in September' on Mars near the Pleiades and the Hyades close to Aldebaran at its stationary point on 9 October; its retrograde motion south of the ecliptic in an orbit tilted with respect to that of the Earth; the orbit of the Moon also swinging round in space so that occultations of Aldebaran will occur in 1959 and 1960, but in 9 or 10 years will be occulting the Pleiades; the orbit being elliptical so that the Moon appears larger or smaller...

Scope and Contents

A copy of star catalogues by Ulug Beigh, Tycho, William of Hesse and Johann Hevelius (3r-22v), with Flamsteed's own tables of the planets (33r-40r), and of the Moon (40r-46v), 48 folios. The volume is undated, but there is reference to observations made by Flamsteed between January 1690 and August 1719. The writing is in various hands, with some alterations by Flamsteed.

Scope and Contents Remarks and tables on proper motion and comparisons of star positions. The volume includes the apparent diameter of the Sun, Moon and primary planets as viewed from the Earth; changes in the obliquity of the ecliptic, 1668-1822, and that observed by the Arab astronomers, 832-1463; unused forms for observational results; proper motion of Arcturus in right ascension from Tycho's observations; rules on aberration of light in calculating the place of a planet; longitude of Cambridge, New...
