_Astronomical Occurrences_

_FOR NOVEMBER, 1827._

(_For the Mirror_.)


Should the afternoon of Saturday, the 3rd of the month, prove
favourable, we shall be afforded an opportunity of witnessing another of
those interesting phenomena--eclipses, at least the latter part of one,
a portion of it only being visible to the inhabitants of this island;
the defect above alluded to is a lunar one. The passage of the moon
through the earth's shadow commences at 3 h. 29 m. 34 s. afternoon; she
rises at Greenwich at 4 h. 45 m. 34 s. with the northern part of her disk
darkened to the extent of nearly 10 digits. The greatest obscuration
will take place at 5 h. 7 m. 42 s. when 10-1/2 digits will be eclipsed; she
then recedes from the earth's shadow, when the sun's light will first be
perceived extending itself on her lower limb towards the east; it will
gradually increase till she entirely emerges from her veil of darkness,
the extreme verge of which leaves her at her upper limb 32 deg. from her
vertex, or highest point of her disc.

We have the following in "Moore," some years ago, on the nature and
causes of eclipses of the sun and moon:--
