The University Observatory is preparing to photograph the total eclipse of the moon which will occur tomorrow night. At 10.17 the moon will enter the umbra of the earth's shadow, and at 12.19 the total eclipse will begin; this will end at 1.48 and at 3.50 the moon will again be clear of the earth's shadow. By photographs the light of the sky will be measured during the eclipse, and the light of the moon eclipsed compared with the moon's light unobscured. The observers will expose also several plates during the eclipse to discover if any hitherto undetected moon may be found as satellite to the moon of the earth.
