Before Yule Moon

 

The Before Yule Moon is the full moon which occurs before the feast of Yule on December 21st. This year that Full Moon falls on December 19th.

There are twelve full moons in a year each has its own name. These names go back over 1,000 years to the times of the monasteries. The monks watched the natural cycle of life including the night sky and divided the twelve full moons into the four seasons.

The feast of Yule occurs on the night of December 21st which is the day of the year when the Sun is at its lowest in the sky and produces the shortest period of daylight of the year. This date can vary from year to year by a day or so. This is known as Sol Invictus (The Undefeated Sun). It was originally a pagan festival. It is possible that after Constantine the Great became Emperor of the Roman empire in 324 CE and converted to Christianity, that he then merged this pagan feast with a Christian celebration.

Christmas Day was not celebrated on December 25th until 336 CE.

A long time ago people watched for the full moon in December; they then had from that date until the feast of Yule to chop down a Yule log from the forest in readiness to burn it from the feast of Yule for twelve nights. They would use some wood from the previous year as kindling to light their fire.

Today we often see the American names for the full moons being used. I however prefer to use the old English names.

Today of course the Yule log has turned from firewood into a cake!!

Mr Baxendell and Variable Stars 2

 

Mr Baxendell and Mr Knott followed up the wish to see people observing variable stars and produced in 1863 what was described as a valuable pamphlet “On the method of observing Variable Stars” by none other as Rev W R Dawes.

Mr Baxendell and Variable Stars 1

 

At the meeting of the Manchester Literary and Philosophical Society of Manchester on the 5th March 1862 Mr Baxendell drew attention to the attempt which is now being made to organise an association for the Systematic Observation of Variable Stars. He was working closely with Mr George Knot of Woodcroft Observatory, Cuckfield, Sussex.

MR Baxendell remarked that the importance of a careful study of the phenomena of Variable Stars will be apparent when it is considered that all the so called fixed stars-our own Sun included- are supposed to have a general similarity of constitution.

It was hoped that the work of Mr Baxendell and Mr Knott would help to organise an association for observing these objects on a well arranged system will meet with a ready response.

Mr Baxendell has just been elected President of the Literary and Philosophical Society of Manchester.

William MacFarlane and his Cooke

 

Dr. William Evan MacFarlane was born on the island of New Caledonia which is located in the Pacific Ocean between Australia and Fiji. He was born in 1866 the son of a missionary.

He was educated in England and entered the medical profession and after first practising in Edinburgh moved to China. However due to civil unrest and then the war with Japan MacFarlane returned to England. He then served with the British army during the Boer war as a medical officer.

In 1903 he obtained the appointment as Government Medical Officer to a large mining district in North Queensland, Australia where he remained to his death. Outside his medical career he was very keen on astronomy.

He took charge of the Walsh Hospital at Irvinebank, North Queensland in 1906 where he also installed on Hospital Hill an observatory which housed a Thomas Cooke of York 7in telescope.

A Cooke for Maryport

 

Maryport Advertiser Friday 18th September 1863

SEPTEMBER 18, 1863. AN OBSERVATORY FOR MARYPORT

The late Mr Daniel Dawson in erecting the tall building at the South-West end of Crosby street, intended to furnish it with a large day and night telescope, camera obscure, and other instruments, suitable for an Observatory; but his sudden death occurring before his object was fully carried out, disappointed the hopes of many of his townsmen. The building is now let at a low rent as a dwelling house, but is still available for the object for which it was originally designed. The wish has lately been revived. It has been suggested to us that a joint stock company, under the Limited Liability Act, might readily be formed—say, at £1 per share; and for £l2O, or £l5O, the building might be provided with suitable instruments, and otherwise fitted up in the interior, so as to make it an attractive place of resort for our summer visitors as well as the inhabitants, on all occasions. We have submitted the plan to Thomas Cooke & Son, the Astronomical Instrument Makers, in York, and their reply to our queries is as follows:

The Telescope you refer to, is of 4 inches aperture. The object glass is manufactured by ourselves,—the tube and eye pieces are French, of which 8 are astronomical and 2 terrestrial. The equatorial mounts are by Adie, of Edinburgh, and are on Professor Smyth's mortar principle. It in furnished with graduated hour circle, and tangent screw motions, and declination circle. The object is quite new and excellent. The price, as above described, is 30 Guineas. As to the Camera, I should require the size of the object, for which it is intended, before 1 can glee you as answer. Yours &c

T. COOKE.


We believe the Telescope here described cost, originally, £80—but was taken back into stock by Messrs. Cooke in lieu of one adapted for an enlarged establishment. It is quite unnecessary for us to expatiate on the advantages to the town generally, in having something which would prove attractive to our summer visitors. neighbouring towns are stealing a march on us, and if we do not bestir ourselves we shall be distanced in the race. If, after securing the necessary astronomical and Mathematical apparatus to satisfy the more philosophical class, a collection of such natural products as the district furnishes were stored up there, it would soon become a local museum, to which the annual subscribers residing in the town could resort at, any time, especially when eclipses, comets, or other astronomical phenomena were to be seen while the strangers would find it a pleasant, as well as profitable place of resort to while away their tedious hours, and give a pleasing variety to their otherwise monotonous occupations. We shall shortly return to this subject. In the meantime let our friends digest some plan of carrying out the object.

Lockyer, Tennyson and a Cooke

 

Westminster Gazette, Monday 12th December 1910

The very interesting little book, " Tennyson as a Student and Poet of Nature," by Sir Norman Lockyer, K.C.8., and Winifred L. Lockyer just published by Messrs. Macmillan (4s. M. net), contains the passages in the late Laureates works which deal with the scientific aspects of nature. "

All such references have been brought together and classified, and by means of notes kindly supplied by various authorities it has been shown how very true to fact Tennyson's descriptions are and how keen and careful an observer be was." Quite a number of prominent scientific authorities have given their assistance, and Lord Tennyson has also read some of the proofs and made suggestions.

In the matter of nature knowledge, Dante, it is contended, is the only poet Who can be even named along with Tennyson. Sir Norman Lockyer, in his preface, tells of his own meetings with Tennyson, and of the great interest the poet always took in matters scientific.

Sir Norman was living in 1864 at West Hampstead, and had erected his 6in. Cooke Equatorial in the garden, and concerning Tennyson he says : I soon found that he was an enthusiastic astronomer. and that few points of the descriptive part of the subject had escaped him. He was, therefore. often in the observatory. Some of his remarks still linger fresh in my memory. One night the moon’s terminator swept across the broken ground round Tycho, he said "What a splendid Hell that would make." Again, alter showing him the clusters in Hercules and Perseus, he remarked musingly. I cannot think much of the county families after that."

In the seventies and eighties Tennyson rarely came to London without discussing some scientific points with his friend. In 1890 Sir Norman visited Tennyson at Aldworth, when he was in his eighty-second year : I was then (says Sir Norman) writing the " Meteoritic Hypothesis" and he had asked for proof sheets. Where I arrived there I was touched to find that he had had them bound together for convenience in reading, and from the conversation we had I formed the impression that he had read every line. It was a subject after his own heart. . . . One of the nights during my stay was very fine, and be said to me " Now. Lockyer. let us look at the double stars again," and we did. There was a 2inch telescope at Aldworth. Tennyson's interest in astronomy was, Sir Norman adds, persistent until his death.

The breadth of Tennyson's outlook upon nature is, as Sir Norman Lockyer points out, only equalled by the minute accuracy of observation displayed. Hundreds of quotations are here grouped together from his poems, and they refer not only to evolution but to the starry heavens, the sun and sunlight, the moon and moonlight, bird-life and song, the insect world, animals and their ways, plants and trees, water and aquatic life, the importance of knowledge, and so forth.

York Observatory and Leeds Mechanics Institute

 

Yorkshire Gazette Saturday 27th June 1840

Visit of the Leeds Mechanics’ Institute to York

On Tuesday last, the members and subscribers of the Leeds’s Mechanics Institution returned the visit which members of the York Society for the Promotion of Popular Science paid to Leeds last summer, when the public exhibition was open.

W L Newman, Esq attended in the Observatory, and there unfolded the wonderful mechanisms for more clearly observing the heavenly bodies.


This was the period just before Thomas Cooke became involved with the York Observatory.

Sir William Keith Murray and his Cooke

 

On December 11th 1858 Sir William Keith Murray (1801-1861) of Ochertyre near Crieff in Scotland purchased a 9 inch telescope from Thomas Cooke of York. The telescope was massive and had a tube that was 13 feet long and was mounted on a stone pier 9 feet and 3 inches tall. Up until this point in time it was the largest telescope that Cooke had constructed and it was also at the time the largest refractor in Scotland.

The weather conditions were often poor at the location of the observatory and Murray was only able to use the Cooke for a short period before his death in 1861. Following his death the telescope was offered for sale unfortunately with no initial interest.

In 1863 a number of gentlemen raised £1,120 to purchase the telescope for the observatory at Glasgow University. It was sited at the Horselethill Observatory and used there until 1939 when the building was demolished. The 9 inch was always referred to as the 9 inch Ochertyre Telescope.

Following the demolition of the Horselethill Observatory a new student observatory was built in the University Gardens to house the 9 in Cooke. This was closed in 1969 after which I have no idea what happened to the 9 inch Cooke Ochtertyre Telescope.

Asteroid 1899 FD discovered with Crossley Telescope

 

The Asteroid 1899 or 452 Hamiltonia was discovered by James Keeler using the 36 inch Crossley Reflector at Lick Observatory on December 6th 1899. The asteroid is named for Mount Hamilton where Keeler was working and where the Lick Observatory is located. 1899 FD was the last asteroid discovered in the 19th century.

The 36 inch reflector had been owned by Edward Crossley of Halifax, Yorkshire who owned Crossley Carpets the largest carpet manufacturer in the world in the 19th century. He purchased it in the 1880s from A. A. Common of Ealing, London. Although it was at the time the largest reflector in England due to the poor observing conditions in the skies over Halifax which was due to the pollution from the many factories in Halifax it was impossible to use the telescope to its best.

In the mid 1890s he donated the telescope to the new Lick Observatory in California. During the late 19th and early 20th centuries the Crossley reflector at Lick proved to be a real trail blazing telescope leading in astronomical research in many different areas. It was also the largest reflector in America until the building of the 100 inch telescope at Mount Hamilton.

Asteroid 718 Erida discovered with Crossley Telescope

 

On December 3rd 1910 Dr Curtiss and Miss Young using the 36 inch Crossley telescope discovered the asteroid 718 Erida. Dr Curtiss took the photograph and it was then discovered by Miss Young checking the photograph. The asteroid has a diameter of about 70 km, with an orbital period of 5.3 years.

The 36 inch reflector had been owned by Edward Crossley of Halifax, Yorkshire who owned Crossley Carpets the largest carpet manufacturer in the world in the 19th century.

The Crossley Telescope and Jupiter's Moon Himalia

 

On December 3rd 1904 Charles Perrine using the 36 inch Crossley reflector at the Lick Observatory in California discovered the 6th moon of Jupiter, Himalia. The moon was named after a nymph on the island of Rhodes and according to Greek mythology she was one of the lovers of Zeus.

Himalia is the 5th largest moon of Jupiter it has a radius of 85 km and lies at a distance of 11.5 million km for Jupiter and takes 251 Earth days to complete one orbit of Jupiter.

The 36 inch reflector had been owned by Edward Crossley of Halifax, Yorkshire who owned Crossley Carpets the largest carpet manufacturer in the world in the 19th century. He purchased it in the 1880s from A. A. Common of Ealing, London.

Joseph Gledhill, Jupiter and a Cooke

 

Joseph Gledhill astronomy assistant to Edward Crossley at the Park Road Observatory in Halifax and using the 9.3 inch Cooke telescope observed Jupiter from November 4th 1869 until December 31st 1869. He observed the Great Southern Ellipse which was easily visible on November 11th 1869.

The 9.3 inch Cooke is still in use today at the Carter Observatory in New Zealand.

Great Comet of 1882 seen from India with a Cooke

 

The great comet of 1882 was first seen in September of that year and was observed and photographed by astronomers all around the world. This included from India.

On September 25th 1882 H Collett from Lahore, the Punjab, India observed the comet with a 4.5 inch Cooke telescope. At 04 hours and 50 minutes local time the comet was estimated to be about 14 degrees long and of unusual breadth. The borders of the tail appear much brighter that the central part.
