Influence of the moon March 23, 2019

Moon in the zodiac sign Scorpio (+ )

Moon in sign Scorpion. The time has come to make the most important decisions. improved mental activity, the increased ability to concentrate on the essence of the problem and the high level of self-criticism are the best way to separate the truly important from the superficial and insignificant.

You can boldly take on new endeavors, develop business plans for new projects and impose on yourself all sorts of obligations that will be feasible.

17 lunar day (+ )

March 23, 2019 at 16:12 - 17 lunar day. The day of feeling the joy of being, finding inner freedom. Ideal for marriage, liberation, sublimation of sexual energy.

Waning Moon (+ )

The moon is in phase Waning moon. The third lunar phase covers the period from the full moon to the beginning of the fourth quarter. On the full moon, the peak of the accumulation of vital and psychic energy is noted, which subsequently gradually decreases.

During this period, activity begins to decrease, there is a frequent change of states, ideas and judgments. When the experience and forces accumulated over the past phases continue to energetically be launched into the implementation of plans.

During this period of the lunar month, the first results of the efforts invested before are already discernible. The mood swings that occur can be related not only to business area but also personal life.

It's a great time to let go of old habits and try something new. In relationships, this is the time of rapprochement and romance at its most high level. The third phase is great for self-development, self-improvement and creation.

Influence of the day of the week (±)

Day of the week - Saturday, this day falls under the influence of Saturn, a planet with a strong, heavy energy, in charge of work and learning.

On this day, it is best to tackle the tasks that have accumulated over the week, draw up plans for the following days, figuratively speaking, to unravel the tied knots. Estimated upcoming costs, as well as business plans, compiled on Saturday, most often turn out to be successful.

Try to hold business meetings on Saturday, never postpone them to Sunday.

During its rotation around the Earth, the Moon is in different provisions relative to the planet and the sun. sunlight falls on the satellite, illuminating its movement. The visible parts of the lunar disk in the sky change during the lunar month, which lasts 29.53 days. This is how the moon phases change.

The lunar month consists of four phases, including the periods of new moon and full moon. In the first and second quarter, the Moon grows, in the third and fourth, respectively, it decreases. Each phase of the moon lasts about 7 days. It is not difficult to learn how to identify them, focusing on the visible presence of the night star. In addition, you can use the lunar calendar with detailed description everyone lunar day and its impact on people and events.

The phases of the moon determine the tides on the planet. Not only the movement of a mass of water depends on these changes, but also the energy of a person, his emotions and physical well-being. Each lunar phase affects the development of situations in all spheres of life: public and purely personal.

The first phase begins with the new moon, which falls in the daytime. Moon, Earth and Sun are in a straight line. With its unlit side, the Moon is turned towards the Earth. At this phase, the moon is not visible from Earth. Therefore, to accurately establish the new moon, they often turn to astrological tables. The new moon is felt as a change, inspired expectation, hope. But it should be noted that for each person the sensations are very individual and the specifics can vary markedly.

Over time, a very narrow thin crescent begins to appear in the night sky - the edge of the surface of the Earth's satellite illuminated by the Sun. The moon at this time is called "growing" or "young month". In general, this is a favorable period for a person. After a possible depression, decline and some relaxation, he is tuned in to a surge of strength and development. In this lunar phase, people usually accumulate energy potential, adjusting to more active rhythms.

The second phase of the moon occurs a week after the new moon. The moon is half lit, with the convex side to the right, which is very easy to navigate by determining the phase. During this period, the energy of the body increases. Emotionally, a person feels more free, liberated, but at the same time his emotions are under control. However, than closer time changes in the lunar phases, the more likely the excess energy in the body, which, without the necessary control, can turn into excitement.

The second phase of the moon ends with a full moon two weeks after the new moon. It's quite easy to define it. Being directly opposite the Sun, the Moon during this period is characterized by the special brightness of its full disk. The full moon is a dynamic period of phase change in human body, the transition from the accumulation of energy potential to its waste.

The third phase of the moon begins immediately after the full moon. Every day the lunar one loses its round outlines, “curving” to the left. By the end of this week, it will only be half-lit. The moon is waning, and with it, as a rule, the accumulated and enthusiasm of a person.

With the fourth phase, the night luminary continues to decrease. The crescent moon gets thinner and narrower until it disappears from the night sky altogether. The state of a person during this period is characterized by a decrease in energy levels, some fatigue, a desire to rest in anticipation of a new lunar cycle.

The moon moves from one phase to the next in an average of seven days, which is why there are exactly seven days in a week - this is the legacy of the first lunar calendars! True, the first compilers of calendars perceived the phase changes of the Moon as a given of nature, without going into explanations of the causes of the observed...

Description of the phase states of the moon

The first ancient lunar calendars were based on observations of the movement of the border of light and shadow, called the terminator, on the surface of the moon. At the same time, four quite clearly visually fixed states were distinguished, called points phase transitions Moons - new moon, the beginning of the month; first quarter; full moon and last quarter also have own names and transitional stages of the lunar phases:

The popular names of the phases of the moon are taken from Dahl's dictionary, as well as from the everyday speech of the north of the Nizhny Novgorod region.
This collection is growing, I think everyone will be interested in messages about others folk names moon phases (forum - green flag on the left).

Libration of the Moon

Theoretically, from the statement that the Moon is turned to the Earth on one side, it follows that we, being on the earth, can see no more than 50% of its surface. Thanks to libration (the swaying of the Moon visible from the Earth), we can look at its poles, and a little peep at what is happening there from its back side, in general, 60% of its surface becomes visible!

The video image on the left shows the results of a numerical simulation of the libration motion of the Moon. The apparent motion of the Moon is simulated, which can be seen by an observer from the Earth's surface (to enlarge the image, click on it - a new window will open).
As can be seen from the figure, this is a rather complex oscillatory-rotational motion determined by three components: the inclination of the lunar axis + the orbital motion of the Moon + the rotation of the Earth. Due to libration for an earthly observer on the lunar disk, only the zenith point of the earth will be stationary, the point above which the earth is visible at the zenith (blue circle in the center of the lunar disk), and the moon's surface itself is in continuous motion (the parameters of the libration of the moon, just approximately correspond to selenographic coordinates of the zenith point of the Earth). The lilac continuously moving cross is the "Navel of the Moon", the point of intersection of the zero meridian and the equator with coordinates (0°, 0°). Cruise "cross" around the "circle" in reality lasts a whole lunar month!

Libration by latitude

Thanks to libration in latitude, we have the opportunity to consider in turn, then the south, then the north pole of the Moon - during the libration movement, the Moon seems to be leaning towards us, then “trying to look higher” (Fig. 1). Libration in latitude occurs due to the inclination of the Moon's axis of rotation to the plane of its orbit, which is also superimposed by the inclination of the orbit itself to the plane of the ecliptic. Total maximum amplitude A can reach 6.68° ( A\u003d 5.145 ° + 1.5424 °) , at the moment when the Moon is at the point of perigee of the orbit at a minimum distance from the Earth.

Fig.1. Libration of the Moon. The libration view of the Moon is presented, in which the lunar South Pole and East End the reverse side of the Moon (green vertical line).
When you hover over the cursor, a picture appears with an angle at which you can see North Pole The moon and its far west side (behind the white vertical semi-arc). The blue circle represents the point on the Moon's surface from which the Earth is visible at its zenith. The lilac cross is a kind of selenographic "Navel of the Moon", a point with coordinates (0°, 0°). (Traditionally, in everyday life it is customary to consider Tycho crater as the "Navel of the Moon" (due to visual similarity), and we have a real selenographic Navel in the figure!)

Libration in longitude

Longitude libration allows us to look at reverse side The moons from the west and east, however, quite a bit on each side (Fig. 1). The optical component of libration in longitude is the result of two phenomena: uneven orbital motion of the Moon and parallax caused by the daily rotation of the Earth.
At orbital movement The moon then accelerates and reaches top speed at perigee 1.052 km/s, it slows down to a minimum at apogee - 0.995 km/s, while the rotation speed around its axis is unchanged. It turns out that at perigee the Moon "does not have time to turn its center towards us" and is forced to show part of its reverse side from the east, at apogee, on the contrary, it seems to rotate faster, "in a hurry", showing the reverse side from the west. The maximum amplitude of such deviations can reach 7.9°.
The parallactic component of libration arises due to the fact that the Moon and the Earth in relation to each other cannot be represented as point bodies at all. The radius of the Earth (6371 km) is significantly comparable with the distance to the Moon - 384400 km!
An observer located at the equator, at the time of the moon's rising, looks at it as if being one degree from the side (for the super moon: Arcsin(6371/356400)/π*180 = 1.02°).
Isn't it an interesting phenomenon? - It turns out that residents of Moscow and residents of Vladivostok, looking at the moon at the same moment, see it differently!

The moon has always carried an aura of mystery and mysticism. And I recently became interested in the elements of astronomical calculations. And how did these two facts coincide :)

What is the phase of the moon?

In fact, this Current state triangle of three bodies - the Earth, the Moon and the Sun. How the Moon is lit in relation to an observer on Earth determines the current lunar phase. The Moon moves in its orbit around the Earth with a period of revolution - 27.554550 days, which is 27 days 13 hours 18 minutes 33.1 seconds. But while the night wanderer does full turn around our planet, which, in turn, manages to go a long way. Because of this, the Moon, having made a revolution, appears to the observer in a new phase.

To catch up with the Sun and appear in the same phase, the Moon needs almost two Earth days. This period between two identical phases of the moon is called synodic month. Its period is 29.5305882 days, or approximately 29 days 12 hours 44 minutes 2 seconds.

Determination of the current lunar phase.

To determine the phase of the moon, you need to take a reference point, i.e. some point in time with a known phase of the moon. Then the phases of the moon will repeat with a known period and they can be calculated. Seems pretty simple, doesn't it?

But there are many nuances.

In fact, a synodic month is an average. Its length can vary within the range of ± 13 hours. The main contribution to this deviation is made by the shape of the Moon's orbit. It has an elliptical character, and the Lena-Earth distance varies from 356,400 km to 406,700 km. For example, in the current month (November 2015) the length synodic month was 29.73 days. Of course, 13 hours is not a large value compared to 29.53 days - the error in determining the phase will be no more than ±1.85%. In general, here, for the accuracy of the calculation, it will be necessary to follow the movement of the Moon's apogee, which shifts with a period of 8.85 Earth years.

Secondly, since we are tied to a specific earth time (we chose a reference point), then to determine the phase of the moon, it is necessary to specify in which time zone the observer is located. This clarification has approximately the same value as the previous amendment. The maximum error in indicating the phase of the moon without specifying the time zone of the observer is up to ±1.6% (12 hours / 29.53 days).

These two contributions are quite significant. There are contributions of smaller orders, but the further we move away from the "reference point", the greater the error will accumulate in the calculation.

I found sets of pictures showing the phase of the moon, but appearance moon, the inclination of its crescent to the horizon line depends on the location of the observer, his geographical latitude. In the northern hemisphere, the waxing moon is turned with its crescent so that it forms the letter "P" when a wand is added to it. In the region of equatorial latitudes, the sickle will lie on its side. And in southern hemisphere Earth observer will see the growing moon in the shape of the letter "C".

Moon phases

First phase of the moon - new moon

Neutral phase. During this period, it is worth refraining from conducting any serious magical rites, because a person feels unnecessary and abandoned by everyone. If today is a new moon, but there may be a slight mental deviation in all signs of the Zodiac. But don't worry, it's normal. The force will grow with the moon, and all the energy will come back.

The second phase of the moon - Growing

At this time, it is best to make plans, but it is too early to start new achievements. Forces are only growing, the body is getting stronger. Luck is back, the reset of all senses has begun.

If today is a full moon, then there is already enough strength to accomplish important things “here and now”. It is recommended to control emotions during this lunar phase. Now emotional background will fluctuate very often, but don't let that scare you. If today is a full moon, then insomnia is possible. If surplus positive energy very high, then pour it into art or sports. Meditation and analysis of everything that happens will help to calm down. Today, solitude with nature is welcome. Now you should take a break and get out to rest in the forest or in the park.

third phase of the moon

Today, the time has come when a person can do absolutely everything that he dreamed of. All things are going according to plan, as planned.

Fourth phase of the moon

Incredible productivity is on the wane. Everything falls out of hand, energy fades. Depression and malaise may return. The moon today negatively affects many people, takes away mental and physical forces. However, there is no need to succumb to melancholy - this period will soon pass, and you will again be able to enjoy the bright colors of life.

The end of the fourth phase is represented by a small crescent in the sky. The mysterious stage when a person is neither happy nor unhappy. Everything starts again. The circle of life closes, as it were, and people feel completely different. During this period, give Special attention his emotional state, cultivate a reverent attitude towards yourself.

Why is it important to know what the moon is now

If you are going to perform this or that magical rite, then it is extremely important for you to know what moon is today. For example, it is customary to read conspiracies and prayers for the growth of wealth, for the birth love relationship. It is believed that the growing night light will be able to attract positive events into your life. On the contrary, it is supposed to get rid of something unnecessary: from a protracted illness, from failure, and so on.

The night luminary affects the representatives of the zodiacal circle in different ways, enhances their qualities. Knowing your features, you can use them for your own benefit. It's even easier to do than to say.

Qualities of the signs of the zodiac:

- leadership, love of life, harmony;
- tranquility, communication, ideas;
- emotionality, amorousness, sociability;
- subjectivity, isolation, vulnerability;
— courage, understanding of rules and laws, creativity;
