A yellow sky

Ragtag Daily Prompt Tuesday: Sol

A mix of colours in the afternoon sky. Do you know why? Have you heard of Rayleigh Scattering? or Mie Scattering?

This could be a combination of Rayleigh scattering, Mie scattering and the angle of the sun.

Rayleigh scattering is related to the chemical composition of the atmosphere and occurs when the particles causing the scattering are smaller in size than the wavelengths of radiation in contact with them (this is why the sky appears blue most of the time).
The yellow sky is likely mostly owing to Mie scattering. Mie scattering is caused by pollen, dust, smoke, water droplets(the most likely culprit in this case), and other particles in the lower portion of the atmosphere. It occurs when the particles causing the scattering are larger than the wavelengths of radiation in contact with them.
The angle of the sun and Raleigh scattering may also be at play, when the sun is low in the sky sunlight passes through more air than when the sun is higher in the sky.
More atmosphere means more molecules to scatter the violet and blue light away from your eyes. If the path is long enough, all of the blue and violet light scatters out of your line of sight. The other colors continue on their way to your eyes.
This is why sunsets are often yellow, orange, and red.

Last on the Card

Last Photo for September 2022

Yes I am back online at last. Thank you to Christine for wanting to share her photo and in her excitement wished to be a temporary host. Thanks also for your good wishes amid my struggles.

So let see what you have for this edition of Last on the Card contributions, your good and not so good photos. Like a lot of people I forget and am surprised at what was the last photo on the four devices I use to take photos. This month is even more of a surprise!!

AS I have always said it doesn’t matter when you post your Last Photos as the last photo for the month is always the last photo.

So let’s see what you have for September 2022

The rules are simple:
1. Post the last photo on your SD card or last photo on your phone for the 30th September.
2. No editing – who cares if it is out of focus, not framed as you would like or the subject matter didn’t cooperate.
3. You don’t have to have any explanations, just the photo will do
4. Create a Pingback to this post or link in the comments
5. Tag “The Last Photo”

Here’s mine

From my Canon PowerShot A1200

Life of a Paper Daisy

This is a Xerochrysum viscosum variety, a Summer flowering daisy. It is also known as Sticky Everlasting, Yellow Paper Daisy, Shiny Everlasting or Golden Everlasting Daisy.

Waiting to greet the day.

Open and feeling good

Starting to feel its age

Closing to protect the seeds and changing colour

It is finally over
