Show THE HEAVENS IN JUNE j By Profeasor Eric Doolittlo of the University of Pennsylvania. ! CENTAURtd,," I puurjtf. Figure 1 The constellation at 9 p. m., June 1. The observer who has looked at the evening sky from time to time during tho past weeks has seen tho brilliant winter groups of stars slowly sinking in tho west, one after tho other, until now only the beautiful Leo remains with us. Moanwhilo tho summer groups have been mounting steadily upward from tho east, the great Bootes, which I leads them all, reaching this month the highest point of the heavens and shining shin-ing out with its magnificent golden star Arcturus, directly overhead. The summer branch of the Milky Way, whose countless stars near Ophinchus J Figure 4 The eclipse of tho sun June 17. - -1 11 inc. I I 1 1 1 n.

Lying along this golden highway are tho beautiful Northern Cross, the brilliant autumn star Vega, the Eagle with its bright star Altair, at A, and in the extreme southeast the striking group of tho Scorpion, which has not yet entirely emerged from below the ground.

This group lies in such a position posi-tion that almost all of its stars sink below the ground at the sumo time, in marked contrast to tho group Bootes, which occupies many hours in disappearing. Shooting Star Showers. Swinging .ceaselessly around the sun in great elongated orbits thero arc tens of thousands of clouds of inotorio matter, which by tidal action havo been stretched out along their paths. In many cases the whole orbit is ono long strip of little particles, not snff iciontlv denso to be seen in any telescope. But there aro several hundred of those streams which lie in such a positiou HORIZON HOftfZOtf - I Figure 3 Appearance of the moon when rising on Juno 3, as seon (a) on the Atlantic coast, and (b) on tho Pacific Pa-cific coast. that the earth passes through them once each year; each little partielo encountered encoun-tered is burnt up by its friction with tho air, and is seen as a shooting star. Because theso particles aro moving parallel par-allel to one another when the earth strikes thorn tho shooting stars of any swarm all appear to dart outward from the same point in the Bky. Tho moBt brilliant showers are those caused by the dense swarms which the earth meets in August and November, but many interesting ones occur also at this time of the j'ear. On any evening even-ing during June the observer, 1)3' careful care-ful watching, may see an occasional star move slowly over tho sky in any direction direc-tion from tho region at B, Figure , probably leaving a train behind it. Toward To-ward the beginning of the month swift-1' swift-1' moving stars may be discovered daTt-ingr daTt-ingr away from the points C. D and E, while on the 26th to "tho 28th a shower of slow moving stars, some of which leave trains behind them, will bo seen to move outward from F. In all of these cases the swarm has becomo so scattered and thinned out that but few stnrB will probably bo seen even after long watching. It is of great interest in-terest to reflect, however, that each one is a little body whose career is thus brought to a sudden end after it has circled for ages around our sun, nnd that now the nature and motions of j even such apparentby erratic and temporary tem-porary littlo objects as those have been louud out by the astronomers. Tho Eclipse of the Moon. During this month wo will be favored with two most interesting eclipses, one of the moon aud ono of tho sun. The eclipse of tho moon, which is caused by our satollite passing into the shadow of the earth, will begin on the ovoning of June 3, nt 6 hours 43 minutes and 21 seconds', eastern standard time. Tho motion of fhe nioon during this- eclipse is shown in Pig. 2. The large circle N S represents the great conical shadow of tlie earth, which extends out into snaco in a direction exactly opposite tlio sun to a distance of 850,000 miles. Tho distance through this shadow at the point where tho moon crosses it is nearly G000 miles; as our satellite is but 2163 miles in diameter it may. therefore, pass completely into tho shadow nnd become dark. In tho present pres-ent eclipse the moon will reach the point B, and the eclipse becomo total at 7 hours 58 minutes nnd 0 seconds; Figure 6 Appearance of tho eclipsed sun as viewed from stations along tho lines AA, BB, etc., of Figure 5. it will reach 0 at S hours 50 minutes 42 seconds, so that the eclipse will remain re-main total, the moon being completely hidden from the light of. the sun for about two minutes moro than an hour. After this tho moon will bogiu to emerge, em-erge, finally reaching the position D and tho eclipso being entirely over at 10 hours J4 minutes 3S seconds p. m. Unfortunately, tho moon at this timo is very low in tho sky, lying nlmost as far below the equator as the sun does at the time of tho shortest day. Its time of rising is. therefore unusually late in the extreme southern' stales, being be-ing 7 hpurs 12 minutes p. m local time, and in tho northern ones 7 hours 25 minutes. Consequently, tho beginning begin-ning of the eclipse cannot bo observed ! in the United States. As the moon rises low, in the southeast, south-east, observers in the eastern states will sec it presenting tho appenranco shown at A, Figure 3; to observers west of the longuudo of Clevolnnd and Atlanta, At-lanta, the moon .will risp totally. eclipsed, while to those ho are farthei H Tvost than Colorado it, will not rise un- H til the total eclipso is over. Ail oo- jiH servers in the United States may, how- H ever, sco tho latter part of the eclipse. H It is probable that our satellite will H not become wholly invisible, but that ! oven when completely immersed in the iM shadow it will shine with a dull, copper-colorod copper-colorod light. The source of this light H is the sunlight which is bent down witli-in witli-in tho shadow by the rim of air sur-rounding sur-rounding tho earth. An observer on H tho moon would sec tho earth at this time surrounded by a brilliant Ting ot red light. If, however, the rogions of the earth along this ring aro cloudy, so iM that the sunlight cannot penetrate it, the disc of the moon may become wholly ivisible. Tho Eclipso of the Sun. IjH On tho afternoon of June 17 there occurs a totnl eclipse of the sun, whicn IjH is only visible aB a partial eclipse ex- NLH copt to observors along tho line AH, HH Vitr 4.
