Full Moon in Mountain Shadow
Image Credit & Copyright: Greg ChavdarianExplanation: On October 15, standing near the summit of Hawaii’s Mauna Kea and looking away from a gorgeous sunset produced this magnificent snapshot of a Full Moon rising within the volcanic mountain’s shadow. An alignment across the Solar System is captured in the stunning scene and seeming contradiction of bright Moon in dark shadow. The triangular appearance of a shadow cast by a mountain’s irregular profile is normal. It’s created by the perspective of the distant mountaintop view through the dense atmosphere. Rising as the Sun sets, the antisolar point or the point opposite the Sun is close to the perspective’s vanishing point near the mountain shadow’s peak. But extending in the antisolar direction, Earth’s conical shadow is only a few lunar diameters wide at the distance of the Moon. So October’s Full Hunters Moon is still reflecting sunlight, seen through the mountain’s atmospheric shadow but found too far from the antisolar point and the Earth’s extended shadow to be eclipsed.

Your Ancient Symbol Reading for the Weekend of October 21
Past Influence that will have an impact on your life
At its extreme Evil indicates a life force that embodies pure malevolence. Fortunately Evil in the extreme is very rare. Generally Evil suggests actions taken that challenge our morality and without regard to the harm that may be done to others. The appearance of Evil signifies a time in which someone is acting out of rage, selfishness, ignorance, or, sadly, sating a mean spirit.
Present Influence that will have an impact on your life
The Tree symbolizes spiritual health and growth. The healthy tree is rooted in a rich, nurturing medium, has a strong trunk from which leaf laden branches fan out to capture the sun’s energy. The Tree represents a healthy spirit entrenched in experience and strengthened by wisdom. It is a spirit that is happy with itself, but continues reaching to become even wiser, more complete, happier, stronger. While The Tree represents a strong and independent spirit, it is also a life-force that owes much of its strength and growth to being surrounded by other healthy spirits.
Future influence whose impact on your life is growing and will be very strong this weekend.
The Storm represents the trouble and discord that creep into our lives from time to time. The storm is represented by a tornado whirling its way across a fertile plain. Tornados are powerful but relatively small, short lived storms, which means that while the turmoil they indicate may be strong it will at least pass quickly. Like the tornado, The Storm is a force outside yourself and beyond your control. During a stormy period you may lose ground. However, knowing one is upon you can certainly help you keep your losses to a minimum, or even turn what might be a disaster into a windfall.
