Abstract
THE APPROACHING OPPOSITION OF MARS.—Mars will be closer to the earth next June than it has been since 1909; the opposition of 1924 will, however, be still closer, the distance being then almost the absolute minimum. The high south declination next June of 26°, making its meridian altitude at Greenwich only 12°, will prevent any useful work from being done in this country. The nearest approach to the earth, 0.45 astronomical units, is on June 18; a week later the autumnal equinox of the northern hemisphere will occur, so that both polar caps should be visible. The earth will remain to the north of the Martian equator till mid-September.
