are; Last quarter, I'd, Ola II. m; new |
Moon, Sth, 3.I3 p. M; first quarter, 10Th, |
LA a. M; full Moon, oath, 2.54 u. m.
The coniunctions of the Moon with the |
planets are With Saturn on the ID, at 9.35 |

the 9Th at l.36 n. m. planet 81 5S III. north, |
with Mercury on the 7th at 1920 p. m, |

junction but unfortunately invisible); with
Jupiter on the 9Th, ut SOB p M, plane, L |
Sun. north with Uranus on the 9Th, at 6.42 |

conjunction also will very unfortunately be |
invisibs); with Venus on the 18th, at Abs |

There will be partial eclipse of the Moon
visible here, during the early morning
hours OF September 9th. The Moon enter
the earth's shadow at liz II. m. +: middle OF
eclipse, 2.is IL, M; Moon leaves shadow
4.2l u. m. At the hight Of the eclipse the
shadow will extend over 79-l0Uths of the
Moons diameter.
The most interesting astronomical event
of the month in which the Moon takes part
will be the occultatiun Of the lrat mngni-
tude star AidebHran, on the morning of the
goth. This will be the second time the
Moon has oceulted Aldebaran during the
current year: the first having been on July
9TH and In daylight, Il circumstance that
restricted its observance to possessors of
telescopes. The September occHltation will,
weather permitting be visible to- any one
with ordinarily good eyes who may leave
| his bod early enough to gaze
thereon. The immersion will take place
about .3S o. M. in this locality, WHEN the
| bright limb of the waning Moon will sud-
denly blot from view the ruddy star. After
| remaining hidden for one hour and 20
minutes the star will suddenly emerge on
| the dark side Of the Moon The late Pro.
| hendary Webb says in his Celestial
| OhiectS;' "OccutatiOns of Aldebaran are
not infrequent as il lies in the Moons
| path they are striking phenomena and, to
| some observers, are apt to exhibit the
singular optical illusion Of projection"
OF this appearance he says; THE
projection of II star upon the
Noon, just before immersion. as if it ad-
vanced in front Of it, is very difficult of eX-
| PLANTATION. South, after II careful cXaminu-
ton of the instances on record, was unable
to come to any satisfactory conclusion It is
m occurrence Of the most capricious kind
which can never be predicted for any star,
eye or telescope, and is evidently an opti-
| cal, not astronomical phenomenon. So
Aldebariln is accompanied by two minute
companion stars, which require Il pretty
good telescope to show them.
