The Weather Network – Rare crescent spring is supposedly Ekinox Super Moon

Friday, March 22, 2019, 20:38 pm – What is "moonbow"

The dog at the equinox night, Cumbria, Andrew K. Andrew, saw a strange phenomenon in the sky.

Taking a camera to run home, he took a picture of that phenomenon and captured it moonbow.


The arch of the moon is an arc of the moon, a rainbow that is seen at night, as the Moon's light shines again with the drops of water or blue drops.

Basically, the light of the moon enters into the water drop or the storm, it is refracted from the back of the opposite side of the drop, so it drops from one drop to the other. and then our eyes (or camera) get it.

As seen in the previous time tweet, the moon's lights are usually white, rather than multi-colored rainbow.

The reason for this is the intensity of the light.

Basically, the light reflected on the Moon is not usually bright enough to detect human eyes to detect colors (stimulating receptive color receptors should be more intense) and the camera with normal shutter speed will not be sufficient enough to lighten the colors.

Some small reds and blues can sometimes step on the moon, using long exposure photography, in the image below:

Moonbows is much strange when your rainbow is common.

The sunlight you need to see the sunlight you need is a combination of:

  • Water drops or rainy fountains
  • Those drops that clear the light path
  • As the light is hidden again, the light of the spectator must be far from the sources
  • The angle of the drops or drops of water inserted into the light is important, with the best angle being 42º, so the light source must be relatively low in the sky.

To see the moon, you need the same conditions as before (changing the sun to the moon), but there are two more requirements:

  • The whole night of the moon (or before or after the whole moon) must be at night, as the maximum intensity or nearness of moonlight, and
  • The night must be very dark, otherwise, to give the greatest contrast between the moon's arches and the night sky. Therefore, the spectator must be far from the main pollution sources of pollution, such as in large cities.

So you can have a rainbow on almost every day of the year, just like the drops and liquids of the liquid, it's much more limited to a more precise lunar month, and you'll have the right place to see it.

Andrew Hewison's reason for showing the color of the images (enhanced, shown above), even though it is thought to be an image that is not a long exposure, for the ideal conditions. Cumbria was a very dark night, on the night of the full moon, but it was also a "supermoon".

It is very difficult to consider a very different size from "normal" to Full Moon and "super" with Full Moon. The Moon closer to the Earth, however, the light reflected from its surface is significantly brighter and more intense.

So, on Wednesday night, the moon of the Super Moon, despite not being the closest moon of the year, was clear enough for the camera to collect more colors than enough light to give it.
