How to Tell Whether the Moon Is Waxing or Waning

Determining whether the moon is waxing or waning can tell you a lot about what phase it’s in, how the tides will move, and where the moon is in relation to the Earth and the sun. It’s also helpful to know where the moon rises and sets during its different phases, in case you want to see it on a particular night. A waxing moon is in the process of increasing how much of it is lit (as observed night to night). i.e., it’s headed toward being a full moon. Waning is the opposite. There are a couple ways to figure out whether the moon is waxing or waning. Although the details are slightly different depending on where you are in the world, the bulk of the method is the same.

[Edit]Steps
[Edit]Understanding the Phases of the Moon
Learn the names of the phases. The moon revolves around the Earth, and as it does, we see different angles of the moon’s illuminated surface. The moon doesn’t create its own light, but rather shines when it reflects the sun’s light. [1] As the moon transitions from new to full and back to new again, it goes through several phases, marked by its recognizable crescent and gibbous (“bulging”) shapes, which are created by the moon’s own shadow.[2] The moon phases are:
New moon
Waxing crescent
First quarter/Half-moon
Waxing gibbous
Full moon
Waning Gibbous
Third quarter/Half-moon
Waning crescent
New moon[3]
Learn what the phases mean. The moon travels the same path around the Earth every month, so it goes through the same monthly phases. The phases exist because from our perspective on Earth, we observe the illuminated portion of the moon differently as it makes its way around us. Remember that half the moon is always illuminated by the sun: it’s our vantage point on Earth that changes and determines what phase we see.[4]
During the new moon, the moon is between the Earth and the sun, and is therefore not illuminated at all from our perspective. At this time, the moon’s illuminated side completely faces the sun, and we see the side that’s in full shadow.
During the first quarter, we see half of the moon’s illuminated side and half of the moon’s shadowed side. The same is true in the third quarter, except the sides we see are reversed.[5]
When the moon appears full, we see its full illuminated half, while the side that’s in complete shadow faces out into space.
After the full moon, the moon continues its journey back to its original position between the Earth and the sun, which is another new moon.
It takes the moon a little over 27.32 days to complete one full revolution around the Earth. However, a full lunar month (from new moon to new moon) is 29.5 days, because that’s how long it takes the moon to return to its position between the sun and Earth.[6]
Learn why the moon waxes and wanes. On the moon’s journey from new moon to full moon, we see a growing portion of its illuminated half, and this is called the waxing phase (waxing means growing or increasing). As the moon then goes from full to new again, we see a diminishing portion of its illuminated half, and this is called waning, which means decreasing in strength or intensity.
The moon’s phases always look the same, so although the moon itself may appear in different locations and orientations in the sky, you’ll always be able to identify what phase it’s in if you know what to look for.[Edit]Determining Moon Phases in the Northern Hemisphere
Recognize that the moon waxes and wanes from right to left. Different parts of the moon are illuminated during waxing and waning. In the Northern Hemisphere, the part of the moon that is illuminated will appear to grow from right to left until it’s full, and it will then diminish from right to left.
A waxing moon will be illuminated on the right side, and a waning moon will be illuminated on the left side.[7]
Hold out your right hand with your thumb out, palm facing the sky. The thumb and forefingers make a curve like a backward C. If the moon fits in this curve, it’s a waxing moon (increasing). If you do the same with your left hand and the moon fits in the “C” curve then it is waning (decreasing).
Remember D, O, C. Since the moon always follows the same illumination pattern, you can use the shape of the letters D, O, and C to determine if the moon is waxing or waning. During the first quarter, the moon will look like a D. When it’s full, it will look like an O. And when it’s in the third quarter, it will look like a C.
A crescent moon in the shape of a backwards C is waxing
A half or gibbous moon in the shape of a D is waxing.
A half or gibbous moon in the shape of a backwards D is waning.
A crescent moon in the shape of a C is waning.
Learn when the moon rises and sets. The moon doesn’t always rise and set at the same time, but changes depending on what phase it’s in. This means you can use the time of moonrise and moonset to determine if the moon is waxing or waning.
You can’t see a new moon because it isn’t illuminated by the sun, and because it rises and sets at the same time as the sun.
As the waxing moon moves into its first quarter, it will rise in the morning, reach its height around dusk, and set around midnight.
Full moons come up when the sun goes down and set when the sun comes up.
As the waning moon moves into its third quarter, it will rise at midnight and set in the morning.[8][Edit]Determining Moon Phases in the Southern Hemisphere
Learn which part of the moon is illuminated during waxing and waning. In opposition to the moon in the Northern Hemisphere, the moon in the Southern Hemisphere will illuminate from left to right, become full, and then diminish from left to right.
A moon that’s illuminated on the left side is waxing, while a moon that’s illuminated on the right side is waning.[9]
Hold out your right hand with your thumb out, palm facing the sky. The thumb and forefingers make a curve like a backward C. If the moon fits in this curve, it’s a waning moon (decreasing). If you do the same with your left hand and the moon fits in the “C” curve then it is waxing (increasing).
Remember C, O, D. The moon goes through all the same phases in the Southern Hemisphere, but the shapes of the letters that indicate waxing and waning are reversed from the Northern Hemisphere.
A crescent moon in the shape of a C is waxing
A half or gibbous moon in the shape of a backwards D is waxing.
A moon in the shape of an O is full.
A half or gibbous moon in the shape of a D is waning.
A crescent moon in the shape of a backwards C is waning.
Learn when the moon rises and sets. Although the moon may illuminate in the opposite direction in the Southern Hemisphere versus the Northern, it will still rise and set at the same times during the same phases.
The first-quarter moon will rise in the morning and set around midnight.
The full moon rises and sets when the sun sets and rises.
The third-quarter moon will rise at midnight and set in the morning.[10][Edit]Related wikiHows

How to Identify a Painting

Learning more about a piece of famous art is easy, but identifying an unknown or obscure painting can be kind of tricky. There are so many paintings in existence that the odds of finding information about a specific image can feel insurmountable. Luckily, you can dramatically narrow down your search by assessing the composition, subject matter, and style. Start by using an image recognition app and reverse image search. Museums and art historians are in a perpetual effort to upload and catalogue paintings and artists online, so it may be easier than you think to find the information you’re looking for!

[Edit]Steps
[Edit]Finding the Artwork Quickly
Use an image recognition app to identify the painting immediately. If you’re struggling to remember an artist’s name or you want additional information on a particular painting, download an image recognition app designed specifically for art. There are several apps for both Android and iPhone that allow you to snap a photo of a painting to search through museum catalogues, university databases, and art history texts. This is the easiest way to find a specific painting.[1]
The two most popular apps for recognizing artwork are Smartify and Magnus. Both of these apps will pull up information about the work’s artist, as well as interesting facts and background information about the composition.
These apps only have access to paintings that have been well-documented and catalogued by curators, professors, historians, and other artists. If the painting is made by a more obscure artist, these apps may not work.
Run a reverse image search if you have a digital copy of the painting. If you’re looking at a painting on your computer or phone, run a reverse image search. Copy and paste the image’s URL into the search engine. Run the search to pull up other websites displaying the painting. This will give you access to a variety of websites that will tell you everything you need to know about the painting.[2]
If you’re using Google Chrome, you can right click an image and select “Search Google for this image” to search the web.
You can download an image and upload it to the engine instead of copying and pasting the URL if you prefer.
The most popular reverse image search is TinEye, but there are several options available online.
Use the signature or monogram to dig online and find the image. Look in the corners of the painting to see if there is a signature or monogram. If the name is easy to read, simply search the artist’s name up online to find the painting. If it’s harder to read, look carefully to see if you can break down the letters and read them. This will let you narrow down the search and figure out who the artist is, which can make it easier to find your specific painting.[3]
A monogram refers to a 2- to 3-letter design containing the artist’s initials. Monograms tend to be more popular among painters working after the 1800s.
Signatures were almost never used before the Renaissance, which began around 1300. Even if you can’t identify a signature, at least you have a baseline for your search![4]
You have to sign up for a free account to use it, but you can use https://artistssignatures.com/ to reverse search for an artist’s signature. This is useful if you think you can read the signature but want to double-check to make sure you aren’t misreading it.[Edit]Assessing the Composition
Ask an expert to identify the era, style, or painter of an image. Email or visit a museum curator, art history professor, or gallery owner to ask if they can take a look at the image. An expert in the field of art will be able to offer insights about the period, style, and give you a better sense for where to look. They may even know who the artist is as soon as they take a look at it![5]
If you’re contacting a gallery owner, try to find a gallery that specializes in the type of art you’re trying to identify. For example, a contemporary abstract piece is going to be easier to identify if the gallery owner mainly focuses on newer artists.
Use obvious clues in the subject matter to narrow down the date. Contemporary painters may paint people or objects from the past, but they can’t time travel! If there’s a train, company logo, digital clock, or some other time-specific component of the painting, this is a great way to set a baseline for your search. You can get a good overall sense for when a painting may have been made simply by asking yourself when an artist would have painted their subject.
For example, there aren’t many painters alive today painting portraits of Spanish aristocrats from the 1600s, and absolutely nobody was painting images of Elvis Presley before 1954!
For example, if there is a small airplane in the background of the painting, you know that the painting must have been made after 1903, since that’s when Wilbur and Orville Wright first successfully flew a plane.
Identify the artistic movement by assessing the style of the painting. There are various artistic movements throughout history that share similar qualities. Determining the movement associated with an image is a great way to quickly narrow down your search since historians group artists from the same movement together.[6]
There are hundreds of movements; if you can’t figure out the movement at first glance, look through museum catalogues and online collections to find similar paintings.
Determine if the artist used acrylic paint to see if it was made after 1940. Get as close as you possibly can to the image. If the color looks flat and the darker colors don’t reflect light, it’s probably oil paint. If the color is reflective, shiny, and looks kind of plastic, it is likely acrylic paint. Acrylic paint wasn’t used in art until 1940, so you have a much smaller period to search through.[7]
If more than one medium was used to produce a work, it is highly-likely that the image was created after 1900. It was fairly rare before this period to combine multiple materials to produce a painting.
This is a lot harder to do if you’re looking at a digital image, but if the colors are almost supernaturally bright or neon, the painting was probably made with acrylic.
Assess the quality of the canvas or paper to determine the date. If the canvas is stapled into the frame uniformly, it is unlikely to have been made before 1900, which is when canvases were first mass produced. You can also assume the painting is relatively newer if it’s is on paper and there’s no tearing, damage, or general wear and tear. Paper is relatively fragile, and it’s unlikely that a fresh piece of paper is particularly old.[8]
If the canvas is hanging loosely on the frame, the painting may have been made prior to 1600. Before 1600, most artists weren’t particularly good at stretching the fabric tight against the frame.
Search through websites and catalogues after narrowing the search. If you know you’re looking for art from a specific time period or movement, go online and search through galleries and websites related to this type of art. Look for paintings that are similar in style, color, and composition. You can also go through museum databases and encyclopedias to find your image to do this as well. With enough luck, you’ll find the artist![9]
Almost every major museum has an online dataset that you can search. Search through these catalogues to find similar pieces that may belong to your artist.
Once you have the artist, finding the specific painting is fairly easy. Museums and universities often catalogue and document the entire body of work for well-known painters, so you should be able to find the specific painting just by poking around online.[Edit]Using Less Obvious Details
Inspect the back of the painting to find notes from previous owners. If you really can’t find anything about an image in your possession using traditional search methods, flip the canvas over and look at the back. If the image is a print or reproduction, it may be listed on the back. If the painting is a family heirloom or was bought at a thrift shop, there may be a handwritten note describing where the painting is from.[10]
Use the other steps in this method first before looking for lesser known details. It’s possible that the painting is a reproduction, print, or mass-produced version of a popular painting.
If you see 2-3 numbers listed in a corner, the painting was probably purchased at a thrift shop or resale store. The employees of these stores often write the price on a back of a work. You’re unlikely to be able to identify the artist or image in this case.
Check the frame to see if you can find a manufacturer. Inspect the frame on the back and look for an imprint, or label. Frame manufacturers often print a company name on the back. If there is a name, contact the manufacturer to learn more about the frame itself. This can drastically narrow down the region and time period where a painting was produced.[11]
If you only have the canvas and there is no frame, check the wood portion of the canvas on the back. Prior to 1900, most artists stretched their own canvases. If there is a signature on the wood frame, it’s probably the artist’s.
This isn’t really a helpful option if the painting is well known or really old, since it was likely re-framed at some point.
Take a large collection from an unknown painter to an art dealer. If you stumble on a large number of paintings and you can’t find a single thing about the artist online or through close inspection, contact an art dealer. Many lifelong artists paint simply because they enjoy it, and it’s possible that you may have stumbled on to a unique collection from a totally unknown artist![12][Edit]Tips
If you want to figure out if a painting in your possession is worth anything, contact an appraisal service. That’s really the only way to authentically confirm whether your painting is worth anything or not.[13]
For many paintings, it will impossible to say definitively who painted the work or when it was made. You may be able to make an educated guess about the era or artist’s background, though![Edit]References↑ https://www.newscientist.com/article/2123373-image-recognition-app-scans-paintings-to-act-like-shazam-for-art/
