Last weekend the sky had a wonderful morning display. I just had to take those photos for Weekend Sky but didn’t post them. The morning sky also held a surprise as well.
21 January skies
It is hard to get the full effect of the sunrise with it’s blazing yellow sun
While to the north, the sun is just reaching the tops of the Eucalypts and our Moon was still shining bright. This photo is from the old little camera which is not being used for morning sky photos any more but still is the small pocket sized camera I will use for my emergency camera if out and about and my main cameras don’t function as I would like.
These are this mornings photos. I was awake about an hour after sunrise this morning. After wild storms over the past few days, the blue morning skies are back, heralding more hot days with afternoon storms.
The northern sky, the sun fully lighting the Eucalypts and a wisp of cloud
Here is the sky on the 26th at around 5pm just before the wild wind and rain arrived
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.
There’s lots of things to make you chuckle in the Aussie bush.
Just this morning I was awake early when the bushmans alarm clock went off.
I popped into the garden, cup of tea in hand and discussed the situation.
We chatted a while with no agreement on waking time.

Goo-Goor-Gaga the Kookaburra
Long ago in the Dreamtime, when the animals were first on the earth which were very much bigger than they are today, there was a time when there was no sun, only a moon and stars.
One day, Dinewan the emu and Brolga the beautiful dancing bird, were out on a large plain arguing and fighting. Brolga got so angry that she ran over to Dinewan’s nest and grabbed one of her large eggs, which she threw up into the sky with all her might. It landed on a heap of firewood breaking, spilling the yellow yolk, which burst into flames. This lit up the whole world below to the astonishment of all the creatures as they had only been used to the semi-darkness and were dazzled by such brightness.
A good spirit who lived in the sky saw how beautiful the earth looked when it was lit up by this blaze. He thought it would be a good thing to make a fire every day; which he has done ever since. All night the good spirit and his helpers collect wood and stack it up. When the stack is nearly big enough, the good spirit sends out the morning star to let them know on earth that the fire will soon be lit.
However, the spirits found that sending out the morning star was not enough because those who slept did not see it. The spirits decided they must have a noise made at the dawn of each new day to announce the arrival of the sun, which would wake the sleepers – but what noise.
Then one day the spirits heard the laughter of Goo-goor-gaga, the kookaburra ringing through the air. This was the noise the spirits were looking for. They asked Goo-goor-gaga that as the morning star faded and the day dawned, every morning would he laugh his loudest to awaken all the sleepers before sunrise. Goo-goor-gaga agreed and has done so ever since – making the air ring with his early morning laughter.
