ECLIPSE OF THE MOON.
OCCUMENiCE*NEXT WEEK. TOTAL PHASE LATE IN EVENING. A total phase of the moon will occur next Sunday night and if the conditions are favourable it should he visible throughout New Zealand. jPeniumbral eclipse will commence at 8'.35 p.m., and will result in an almost imperceptible darkening of the lunar disc. At 9.48 p.m. the eclipse will commence so far as the ordinary observer is concerned, for at that time 'the earth’s shadow will make its first contact with the lunar disc.
As the edge of the shadow is invariably hazy and ill-defined, it will be possible, if one knows at what part of the disc the gradual darkening at this spot for one or two minutes before the actual eclipse is timed to occur. The shadow will first be noticed at the lower right-hand side, close to the bottom part of the disc. From the moment of first contact the shadow will steadily grow in extent until, at 11.1 p.m., the moon will be entirely immersed in the shadow. From this time until 12.18 a.m. totality will continue. During this time the moon may entirely disappear from view or may be visible as a reddish ball, according as the shadow is black or reddish. In the total eclipse visible in New Zealand last June some beautiful colours were observed in the eclipsed moon, and the edge of the shadow was so light as to lead many astronomers to aver that the eclipse had not been total. The moon will commence to emerge from the earth’s shadow at 12.18 a.m., and the shadow will then rapidly decrease until 1.32 a.m., when it will finally leave the lunar globe. Penumbral eclipse will, however, continue until 2.45 a.m. on June 4.
The magnitude of the eclipse will be I,247.times the moon’s diameter, and it therefore appears unlikely that there will be any doubts such as arose last year as to whether totality actually occurred. This eclipse is the second of five eclipses that will occur during 1928. There can never be more than seven eclipses in any year, nor fewer than two.
