The house thought to be Crabtree's home at the time of the observation of the transit. On 9 June 2004, the day after a transit occurred as predicted by Horrocks, a commemorative street nameplate in memory of William Crabtree was unveiled at the junction of Lower Broughton Road and Priory Grove which marks the northern boundary of Crabtree Croft ...
A transit of Venus takes place when Venus passes directly between the Sun and the Earth (or any other superior planet), becoming visible against (and hence obscuring a small portion of) the solar disk. During a transit, Venus is visible as a small black circle moving across the face of the Sun. Transits of Venus reoccur periodically.
For the transit of Venus on 3 June 1769, Chappe's destination was the Mission of San José del Cabo at the tip of the Baja California peninsula in modern-day Mexico. The journey and observation were uneventful. However, as the expedition was packing to return, an outbreak of fever (possibly yellow fever) hit the area. Chappe stayed to tend the ...
The next time a mutual planetary transit or occultation will happen (as seen from Earth) will be on 22 November 2065 at about 12:43 UTC, when Venus near superior conjunction (with an angular diameter of 10.6") will transit in front of Jupiter (with an angular diameter of 30.9"); however, this will take place only 8° west of the Sun, and will therefore not be visible to the unaided/unprotected ...
Tupman's official journals for his time spend at Greenwich from 1872–1880 and his time at the Honolulu observing station, as well as his private journal for 1875, are available online. [ 7 ] Tupman (and his wife Rebecca, who he had married in 1876) observed the 1882 transit of Venus from Burnham near Christchurch , New Zealand.
The black drop effect was long thought to be due to Venus's thick atmosphere, and indeed it was held to be the first real evidence that Venus had an atmosphere. However, it is now thought by many to be an optical effect caused by the combination of the extreme darkening of the Sun's disk near its apparent edge and the intrinsic imperfection of ...

Kepler's tables had predicted a near-miss of a transit of Venus in 1639 but, having made his own observations of Venus for years, Horrocks predicted a transit would indeed occur. [ 19 ] Horrocks made a simple helioscope by focusing the image of the Sun through a telescope onto a plane surface, whereby an image of the Sun could be safely observed.
