August 4 5h 00m a. m. The Earth passes the aphelion point and reaches its farthest distance from the Sun on the night of July 23rd, about midnight, Pacific time. There will be three eclipses during July and August. As is always the case when three eclipses occur in so brief a time, the first and third will be eclipses of the Sun, and the second an eclipse of the Moon. The first, a partial eclipse of the Sun, will occur in the early morning of July 21st, Pacific time, and will be visible in far southern latitudes only. The second is a total eclipse of the Moon, on August 4th, The beginning will be visible in the central and western portions of North America, and the eastern portions of Asia, and Australia, and the ending will be visible in Alaska and through Asia and Australia. The middle of totality will come at 5h. 1m. a.m. Pacific time, and the beginning and end of totality not quite an hour before and after that time. For the western part of the United States the Moon will set and the Sun will rise during totality. The third is a partial eclipse of the Sun, on the afternoon of August 19, Pacific time. The eclipse will be visible mainly in the north polar regions, but it may be seen as a very small partial eclipse late in the afternoon in that part of the United States west of the Missouri and north of 40° latitude. The maximum obscuration is about one-third of the Sun's diaraeter and in regions far north of the United States. As seen from any part of the United States, the maximum obscuration will be much less. At the beginning of July, Mercury is an evening star, setting an hour and one-half after sunset, and the interval is more than an hour until well after the middle of the month. So the first half of July affords the best opportunity of the year for seeing the planet as an evening star. The greatest east elongation, 26° 39′ is reached on July 15th, and is much above the average as the planet reaches its aphelion only a |
