Having observed successfully the eclipses of 1898 January 22, in India, and 1900 May 28, in Algiers, and my husband having been sent to Mauritius as the representative of the Royal Observatory, Greenwich, to observe the eclipse of May 18 last, I determined to accompany him, and to take with me the instruments which we had used in 1900. By the great kindness of Mr. G. J. Newbegin, F. R. A. S., I was also furnished with a 4¼-inch Cooke photo-visual telescope of 71 inches focus.

I had again the honour of being nominated one of the observere for the Joint Eclipse Committee, the station allotted to me being at Santa Pola, on the south-east coast of Spain. On the 9th May I left Edinburgh, and sailed from Tilbury on the 11th in the Orient steamship “Oruba,” accompanied by Mr. Thomas Heath, First Assistant at the Edinburgh Royal Observatory. who was. going to Santa Pola to observe the eclipse on behalf of the Royal Society of Edinburgh.

In the month of August, 1897, I was invited by the Joint Permanenta Eclipse Committee to take part in observing the total solar eclipse which occurred in India on 22nd January of the present year. The preparation of the equipment, which will be described further on, was at once proceeded with, and by the sanction of the Univer­sity authorities and the Secretary for Scotland I was granted the necessary leave of absence from the University and the Royal Observatory.

The expedition to which this report refers was one of those organised by the Joint Permanent Eclipse Committee of the Royal Society and the Royal Astronomical Society; it was supported by a grant made by the Government Grant Committee. Guelma was chosen for the site of the observations, as being an inland station between Sfax, which was selected for an expedition from the Royal Observatory, Greenwich, and Philippeville, which it was at first expected Sir Norman Lockyer would occupy. Guelma is 58 kilometres from Bona, 65 kilometres from Philippeville, 55 kilometres from the nearest coast of the Mediterranean Sea; it lies at a height of about 1200 feet above sea-level on the south side of the Valley of the Seybouze, amongst hills which range in height from about 3100 feet at 13 kilometres to the north, to about 4700 feet at 11 kilometres on the south, where lies the celebrated mountain, Mahouna, “the sleeping lady,” so called from the resemblance of its silhouette to the form of a woman.

Preliminary Account

An expedition to observe the total solar eclipse of August 30 having been sanctioned by the Admiralty, it was arranged, in concert with the Joint Permanent Eclipse Committee, that a party from the Royal Observatory should make observations at Sfax, a town on the north coast of Africa, about 150 miles south of Tunis. The programme of observations consisted of photographs of the corona on various scales for coronal detail and streamers, and photographs of the spectrum of the corona and chromosphere. The observers from Greenwich who took part in the expedition were Sir William Christie, Mr. Dyson, and Mr. Davidson. Professor Sampson, Mr. J. J. Atkinson, and Captain Brett, D. S. O., generously volunteered their assistance and shared the work of erecting and adjusting the instruments as well as of the observations on the day of the eclipse.

Daily Time

An expedition to observe the total solar eclipse of May 28 having been sanctioned by the Admiralty, it was arranged, in concert with the Joint Permanent Eclipse Committee, that the Royal Observatory party should take photographs of the corona on a large scale for structural detail, and on a smaller scale for the coronal streamers, and should also photograph the spectrum of the “flash” and of the corona. The programme thus naturally divided itself into two parts, Mr. Christie, assisted by Mr. Davidson, taking charge of the first part, and Mr. Dyson of the second. The party are much indebted to the Portuguese Government for the liberal arrangements made for the conveyance of the observers and their instruments in Portugal free of all charge to and from their observing station at Ovar, and for the great assistance rendered in erecting the instruments, and for a daily time-signal from the Lisbon Observatory direct to the observing station.

The Scottish Expedition to observe the Total Solar Eclipse of May 28 consisted of Professor Copeland and Mr J. B. M'Pherson, Engineer to the Royal Observatory, Edinburgh, who were sent out by the Joint Eclipse Committee of the Royal and Royal Astronomical Societies; Mr Franklin-Adams, who joined the party as a volunteer observer; and myself, who had the honour of being sent out by this Society. The special object which we had set before ourselves was, of course, the attempt, if possible, to add something, however little it might be, to the sum of known facts concerning the constitution of the solar corona.

AbstractWe present the results of the analysis of a movie taken over a small field of view in the intermediate corona at a spatial resolution of 0.5“, a temporal resolution of 1 s and a spectral passband of 7 nm. These CCD observations were made at the prime focus of the 3.6 m aperture CFHT telescope during the 1991 total solar eclipse.
