Abstract
THE TOTAL ECLIPSE OF THE MOON, AUGUST 23.— Though lunar eclipses have lost the degree of astronomical interest and utility formerly attached to them, the general observer may still be expected to find the same amount of attraction as in past times in watching the physical features of a total eclipse of our satellite, well visible at a convenient hour of a summer's night. On Thursday evening, August 23, with favourable weather such a phenomenon may be witnessed, throughout its continuance, in this country as in other parts of Europe. The first contact with the penumbra takes place at 8h. 3.7m. Greenwich mean time, and that with the dark shadow at 9h. 13.7m., about 59° from the northernmost point of the moon's limb towards the east; the total phase begins at 10h. 19.1m., and ends at 3.7m. after midnight; the last contact with the shadow occurs at 1h. 9.1m. A.M. (August 24), about 112° from the northernmost point towards the west, and that with the penumbra at 2h. 19'1m. With respect to the earth's true shadow the eclipse, therefore, continues 3h. 45m., and the moon is totally immersed in it for 1h. 45m., the middle of the eclipse at 11h. 11m. P.M. When she first encounters the earth's dark shadow her altitude at Greenwich is 18°.
