Flash Spectrum

In a general way the conclusions arrived at from the discussion of the spectra obtained in 1898 are amply confirmed and extended by the present results. It is now shown that every strong dark line of the solar spectrum exceeding Rowland’s intensity 7 is found in these spectra as a bright line; and the great majority of the bright lines of the flash spectrum, excluding hydrogen and helium lines, coincide with dark lines of intensity not less than 3. Most of the bright arcs of the flash spectrum are well-defined narrow lines admitting of considerable accuracy in the measures, and the present determinations of wave-length indicate that the coinci­dence of the bright lines with the dark lines is exact within ·05 t. m. for all the well-defined lines.

This expedition was one of those organised by the Joint Permanent Eclipse Committee of the Royal Society and the Royal Astronomical Society, funds being provided from a grant made by the Government Grant Committee. The following were the principal objects which I had in view in arranging the expedition:— To obtain a long series of photographs of the chromosphere and flash spectrum, including regions of the sun’s surface in mid-latitudes, and near one of the poles.
