The President’s Message

To the Members of AOS,

While October leaves us with full buckets and pockets of Candy Corn and witches’ potions, this year’s celebration of Halloween, short for All Hallows’ Eve, is an astronomical holiday otherwise known as Cross-Quarter Day (CQD).  CQD is the midway point between the Autumnal Equinox and the Winter Solstice.  DO YOU KNOW THE OTHER 3 CQD’s?  (SEE ANSWER KEY AT END)

October also leaves us with a special Partial Lunar Eclipse, eerily tied to the Halloween cycle.  For us here in the Nassau County area, it will only be about 25% covered, but enough to cast the eerie red tinge to the All Hallows Eve Full Moon.  Following All Hallows Eve is All Saints Day November 1, 2023 and the beginning of the Holiday Season.

Moving through both time and space, with November upon us, we are approaching the Winter Solstice. For the people that reside South of the Equator, the warm air brings in their Summer but for us that lie North of the Equator, the nights grow longer, and with celestial luck, the skies will be clear and dark.  Clear enough to see this month’s Astronomical Events:
