M^r Crisp called to discuss new Altaz dome

RH says..... This image shows the dome of the Altazimuth Pavilion today, although it no longer contains Christie's altazimuth telescope, the Universal Transit Circle. The building wasn't completed until 1899 and the weathervane was only put up in 1901. It shows Halley's Comet as depicated in the Bayeux Tapestry, in rememberance of Edmond Halley, the second astronomer royal, and in anticipation of the 1909/10 return of the comet.

M^r Jordan Super^t of Greenwich Park came down about proposed modification to R.O. Boundary. Gave him a litho. plan of R.O. showing modifications proposed including enclosure for Magnetic Pavilion E. side of Blackheath Avenue.

RH says..... Liographic plans of the Observatory's site seem to have been produced from time to time, on behalf of the Admiralty's Department of Works. The proposed new enclosure is what became the Christie Enclosure, about 320 meters east of Flamsteed House, which was initially home to the Magnet Pavillion but in the 1930s had buildings containing the reversible transit circle, Cookson zenith telescope and Yapp 36-inch telescope.

RH says..... The RAS council meeting included a contribution by Frederick Howlett, a rector and astronomer dedicated to the study of sunspots. This caught my eye as I have recently been looking at the history of solar observation for a display called 'Solar Story' opening at the ROG in January. This will coincide with a new planetarium show, Secrets of the Sun, and the ROG's contribution to a citizen science project working with the data of the STEREO mission. It is a good opportunity to highlight the work of Maunder and the observatory's magnetic department.

Went to Troughton & Simms about Astrographic micrometer, Posⁿ mic. of 28in telescope, new Altazimuth &c. M^r Simms gave me a specimen of Mantics’[?] ordinary dense flint (very transparent) for new photo-spectroscope.

Col. Wheatley (Bailiff of Parks) called with M^r Jordan (Super^t Greenwich Park) with reference to improvement of west boundary of Obs^y from point of view of Park. He proposed to access[?] portion of garden between existing fence & west wall of Lawn & west side of garden house. I told him that questions of modification of boundary should be considered as a whole & explained to him the modification I should propose round Physical Obs^y and on east side. It was understood that he would raise the question of the alteration of west fence.

Sir H. Thompson dined with me at R.S. anniversary dinner.

D^r Dyson made an observation of the Sun’s Transit across two plumb lines to determine the Meridian line of the New Altazimuth. The result agreed closely with the line obtained by M^r Nash by Magnetic Observations. The two plumb lines were 37^ft apart. The Centre of the Sun & the second limb crossed the line 5^s too soon: giving an error of 2^s. M^r Nash’s line was compared with Col: Tupman’s & agreed well.

Frank Dyson, Chief Assistant

RH says..... Christie's plans for the Physical Observatory had always required that a small parcel of land from the Royal Park be brought within the Royal Observatory's boundary. His tagging of this issue onto the question of improving the western boundary around Flamsteed House is decidedly sneaky.

30 November, St Andrew's Day, is the anniversary of the Royal Society's foundation in 1660: 2010 (or technically 1 December 2009 to 30 November 2010) will be a celebration of the Society's 350th anniversary.

Lieutenant Colonel Tupman, mentioned by Dyson, had had a connection with the Royal Observatory in 1874, having organised one of the transit of Venus observing expeditions, but archives from the Observatory in Cambridge show that he continued observing at Hillfoot Observatory in Harrow.

Meeting of Ratcliffe Trustees[?] at 9 a.m.

RH says..... This entry is rather illegible, but my reading suggests that this relates to a meeting of the managers of the Oxford Radcliffe Observatory.

Meeting of Blue Coat Trustees at 5.30

William Christie, Astronomer Royal

RH says..... The Blue Coat charity was founded to provide schooling to poor children, who would wear the eponymous blue coats to school. The meeting that Christie attended probably related to the Greenwich Blue Coat School, now incorporated into the Blackheath Bluecoat School.
