Dawn in Three Parts

I was just reading Midmarsh John's latest post Friday morning with his photo of a gorgeous dawn sky holding a crescent moon and I realized that some 7 or so hours after he had taken his picture, I had taken some of the same crescent moon at dawn over here on the other side of the Atlantic.  The sky in John's photo has flaming orange clouds with a slim crescent above.  Be sure to check it out.  The image below is more sedate with rosy fingers reaching for the moon over a dove grey sea and clouds. The rays that converge on the sun like this are called "crepuscular rays".
Part 1.  Slim crescent moon chased high into the sky by the rising sun.
Ten minutes later, the sun was high enough to illuminate the grey clouds.
Part 2.  Coral lining in grey clouds.
I turned to the west and saw that dawn had reached across the heavens with sunrays converging at the spot opposite the sun.  Rays like this are called "anticrepuscular rays".  Here is nice website that talks about sunrays and how to see them best.
Part 3.  Dawn sunrays in the western sky.
I took the last 2 photos above from the sunset balcony, yes the very balcony that has been the site of the 2 most recent projects.  The photo below shows the sunset balcony with the upsidedown roof underneath it and the sunshade above it.
Come on up!
 I am really pleased with how the sunshade turned out.
Sunshade extending from under the eaves out to the rail of the balcony.
Just look at all that nice shade.
Twenty-eight minutes past high noon.  The shade is quite pleasant.
The hot-glue gun worked like a charm to hem the edges of the shade cloth.
I wrapped the cloth under the frame on the south (here) and north ends, and secured it to the frame using eyehooks and carabiners.  The hardware is stainless steel to minimize corrosion in the salt air.
I like how the shade cloth lets some light through, so that it doesn't make the inside of the cabana too dark.
View to the west.
Below is a detail showing the hemmed end with the butterfly clip, carabiner and the eyehook screw.
The carabiners will make it easy to take the cloth down if a storm comes up.  I can reach all 11 carabiners without a stool or ladder.  I really don't want to be standing on a ladder with the wind whipping around!
It took us not quite 3 days from start to finish for the sunshade project.  Amazing how quickly it can go when you have the materials at hand.

Sea and Shade and Sun

According to the Weather Underground Almanac, the hot weather in our part of Belize lasts from May through September, and this September is certainly not letting its end of the bargain down!  The high for the last several days and forecast for most of the upcoming week is in the low 90s F (30 C).  Because we face east toward the Caribbean, the morning sun comes straight in our veranda from dawn (6:00 AM +/- 30 min) until about 10:00 AM.  As you can imagine, this yields considerable undesired solar gain.  We didn't want to plant trees to shade the east side because that would block the sea breeze and our view.  So we decided to try our hand at making solar shades that would meet our requirements.  Namely they should withstand the UV, the wind, and the salt air and would be easy to use, inexpensive, and relatively simple to make and maintain.  We don't ask for much, do we?  Below is version 1.1 of the shades in the first 4 of 11 sections of screened veranda.
Shades from Keystone's (cheaper) version of Coolaroo shade fabric.  Can't you just feel the heat from the blazing sun?
The shades need to adjustable, yet anchored at each level to keep them from flapping in the breeze. 
We have 3 levels for the shades:  fully furled, 1/3rd down, and fully unfurled.
Version 1.0 was made with cheap cup hooks for hanging and anchoring using the butterfly clips alone.  Version 1.1 upgraded the cuphooks to stainless steel eyehooks and added stainless steel carbiners to make it easier to adjust the levels.
Stainless steel eyehooks and carabiners attached to the black plastic butterfly clips anchor the shades at the 1/3rd unfurled level.  This height was determined as the maximum height I can reach without using a stool - very critical to meet the "easy to use" requirement!  Luckily, that also keeps the shades high enough so they don't block the view.
I cut the Keystone fabric so that the selvedged edges were the top and bottom of each section.  This particular weave of shade fabric blocks out 90% of the UV light, which is a big plus.  I left the cut edges unfinished and I don't think I will bother to finish them; I may trim off some of the errant threads if they get too unruly.
The shades puff out in the breeze, but are securely anchored with the hooks and carabiners.  Simply unclip the carabiners, let the shade unroll, and reclip at the bottom to get the full shade effect.
The butterfly clips were easy to attached to the fabric using needle nose pliers .
There is a pattern of little prongs that poke through the fabric and then through the holes on the other side of the clip when you fold the clip over, thus securing the clip to the fabric.
 We can tell a tremendous difference in temperature of the side of the veranda that is shaded compared to the unshaded side. Once we were happy with the shades, I bought the fabric and other supplies to do the rest of the veranda.  For the entire length of the veranda (34 ft), the fabric was about $70, stainless steel hooks and carabiners were $25, and butterfly clips were $10; all on Amazon with free shipping.

So what do you do on a hot morning without a sea breeze to help keep you cool?   You get in the water, silly!  This morning, Dennis and I got in the water, which is quite shallow in front of our place.  I took my camera with me as we waded to the south of the dock.
I took this photo standing in mid-thigh deep water about 60 ft off shore.
We waded in the water to the south past our property.  And then I swam a bit longer once I handed the camera off to Dennis.  The only people we saw were in 2 boats - one was a tour boat with Percy at the helm, probably on the way to give his 2 clients a tour up the Monkey River.  The other boat had our neighbor Lloydie and his lady Diana in it going to the village for the day.

We saw a couple of stingrays, some small fish, and whelks, but not much else.  The water was flat and clear - and very refreshing.  An idyllic day in South Englishtown.
