Wednesday’s beautiful sunset at Burrow Beach with vivid crepuscular rays. A rare enough sky that doesn’t appear often here.
Altocumulus lenticular and stratocumulus clouds dominated as distant virga/rain showers were falling.
Altocumulus floccus in the evening sky,it preceded a larger area which a thunder storm and rain arrived later.

I am almost finished with a short introductory course via the edX platform Backyard Meteorology: The Science of Weather"
pll.harvard.edu/course/backyard-meteorology-science-weather realizing how little I know about what makes weather systems 'work'. Excellent, well-presented course for newbies.
It was a lot to absorb for this non-scientific brain, which I wish I had more of, i.e. scientific brain :D
Apart from the more obvious cloud formations, such as the one featured, I am clueless about others and so I joined
My next and last assignment is a weather prediction from my own observations without watching the official forecast :) Gonna be fun. Blue sky every day so far.
Now thinking of doing the 'Navigation course'.

I've been out in isolated desert areas and, without my GPS unit (which I have dropped and it now has a smashed screen), I would be utterly lost. And, no, I wouldn't want to be a trek leader out in the desert, with a bunch of people having to rely on my 'navigation skills', no matter how many courses I would have done.
Now, the following is interesting for those, like me, living in the Southern Hemisphere:

Quote ‘Steps one should take when they find themselves lost”
Use the stars. Your latitude is equal to the elevation of the celestial pole above the horizon. At present, Polaris marks the North Celestial Pole.
There is no bright star at the South Celestial Pole now, so more astronomical expertise will be required if you can’t see Polaris.
There, must try to fix the screen of my GPS unit …
I have two replacement screens and may try my trusted photographic repairers to try to replace the screen.
First Nation’s people in Australia travelled considerable distances across isolated areas in order to trade goods. They found the waterholes again and managed to return to their homeland, if necessary, all without technology. Many lives may have been lost, on land and on sea, until they figured it out and passed the knowledge down from generation to generation.
Makes one wonder how much common sense we have lost.
A nice sunset over the fields of Seeley's Bay.
The scientific names for clouds are in Latin, so I ran with that for the title and added the Latin words for sunset.
Here's the breakdown...
Altocumulus - From the Latin altum, which means height, upper air, and cumulus which means an accumulation, a heap, a pile.
Floccus - tuft of wool, fluff, nap of cloth
Solis - sun
Occasum - setting, going down; death

A daytime view of the same picture next to this one, with some amazing altocumulus clouds formations in the skies.
This cloudscape shows a fine example of potential instability. With virga falling after sunrise, the air cools through evaporation and thus increases conditions for later thunderstorm development.
Image taken at 7:43AM.
I had to check Wikipedia to find the name of these clouds Whatever the name there still pretty interesting looking I think.
Stunning skyscape. Sometimes it's rewarding to direct your gaze upwards.

Altocumulus Castellanus Close up. I think this is too big to be Altocumulus Floccus. In any event there was quite a big thunderstorm a couple of hours later.
A prolonged and extensive display of altocumulus castellanus and altocumulus floccus over Exeter on the evening of 22 August 2017. These were the precursor to intense thunderstorms over northeast England the following morning, which produced flash flooding in a number of places. A parhelion (mock sun) is also visible in cirrus cloud near bottom left of the photo.

Wisps of cirrus fibratus were also visible above the medium-level clouds for a while.
