International Observe the Moon Night

   Saturday October 20th is International Observe the Moon Night. That evening the 12-day old waxing gibbous Moon rises around 5 pm local time and will be over the southeast horizon during the evening hours. Joining the Moon are several planets – all located to the west, right, from the Moon. Early, shortly after sunset the inner planet Mercury will be just above the western horizon. Moving east from Mercury is Jupiter, then Saturn, then Mars. The planet Neptune is only a few degrees above the Moon but because of the Moon’s reflected light Neptune will not be visible.

October Moon at Apogee and at Descending Node

   Wednesday October 17th the 9-day old waxing gibbous Moon will be crossing the ecliptic moving south. This is known as the descending node, one of two intersections the Moon’s orbital path (dark green line) has with the ecliptic.
   Also on the same day the waxing gibbous Moon reaches apogee, (greatest distance from Earth), on Wednesday October 17th. At that time the Moon will more or less be at a distance of 31.69 Earth diameters, (251,175 miles (404,227 km), from the Earth.

Moon in a Face-Off with Taurus


   Sunday September 30th the 20-day old waning gibbous Moon will be within 1-2o from the reddish star Aldebaran in the open star cluster the Hyades. The Hyades are a v-shaped group of stars making up the face of Taurus the Bull.
Aldebaran is at the tip of one of the
lines making up the v-shape and, with its reddish color, represents the ‘angry eye’ of the Bull.

Asteroid Vesta Passes Saturn

   For the next several evenings Asteroid Vesta will be passing within 2-3o from the outer planet Saturn. Currently Vesta is only a couple of months past opposition, June 20th, and is still bright enough to be seen and followed as its position relative to Saturn slowly changes each evening. Saturn has an apparent magnitude of 0.47 while Asteroid Vesta has an apparent magnitude of 7.0.

   With binoculars Vesta is visible under dark enough skies and with careful observation and a star map of that area the motion of Vesta may be followed. In that same general area, within the field of view of 10×50 binoculars, at least 3 Messier objects may also be seen. The Lagoon Nebula, M-8; The Trifid Nebula, M-20; and open star cluster, M-21.
   This animated graphic shows a binocular view of Saturn and Vesta each day from September 25th to the 30th.
