Subcategories of Twilight and more
Use your pinky finger to apprehend the sky dome. Imagine yourself at sea, out of sight of land, on a calm day. Keeping your arm extended, place your pinky-tip on the horizon due east, raise your arm directly overhead. The average sized pinky-tip will have spanned 90 of its lengths. The distance measured from the horizon to directly overhead, the zenith, is 90 degrees of sky dome, about one pinky-width per degree, one-fourth of the entire 360 degrees of sky around your spot on the globe.
The apparent width of the sun disk from earth covers 1/2 degree of sky dome. The disk center point moves 15 degrees per hour (360/24 = 15). Using these facts to estimate time to sunset is relatively straightforward. Estimating time to dawn from the sky is more difficult. This graphic, “Twilight-dawn subcategories,” is a way to grasping what happens. Your position on the earth globe affects the experience. For example, at northern latitudes above 60°34′ summer nights never become darker than civil twilight because the sun’s midpoint never drops lower than 6 degrees below the horizon. Civil twilight lasts all night long summer times in parts of Sweden and Finland.
The date-time stamp on the first photograph of this series is 6:46:23 am, Cocoa Beach sunrise for February 1st was 7:09:40, 00:23:17, 23.283 minutes in decimal notation, later. This duration divided by 60 minutes in an hour and multiplied by the sun’s apparent velocity across the sky (15 degrees per hour) and minus the .25 degree between sun’s center and disk edge, gives the sun’s center as 5.57 degrees below the horizon: this is a photograph of the sky a minute or so after the sun passed civil dawn into civil twilight. I am not more exact because this calculation does not account the deviation of the sun path from due east at this latitude, lengthening civil twilight duration by almost a minute.
The following photograph is time-stamped 7:05:06, 4.567 minutes until sunrise, sun center is just below the horizon, setting the dark clouds of the previous photograph fleetingly on fire.
Sunrise has passed in the following photographs, obscured by clouds and making for a great light show. Enjoy!!

Sights along Cocoa Beach
Even on vacation I rise early to better enjoy the day. This year’s escape from the Ithaca winter, at Cocoa Beach, up at 5 am with a beach chair and oranges in hand I walked in darkness from our beach side resort to the tide high point. My time occupied by sky watching I peeled, and ate, oranges while locating stars through the wind blown clouds. When the barely perceptible dawn light began I packed it up to find Pam, who asked to be awake for sunrise.
This day, we ate breakfast from ready to eat food purchased from the Publix market close by on Atlantic Avenue, and caught up with the news craziness. We had a day at the Kennedy Space Center planned after the sunrise walk.
Here is our view while walking north along the tide line. In the far far distance are the Kennedy Space Center Vehicle Assembly building and a space launch gantry. Follow the shoreline to find the pier.
We walked nowhere near the pier, barely visible, not to mention Sam Shepard park. The pier and park are a day’s walk. We had a few hours free before our “Lunch with an Astronaut” event at Kennedy Space Center.
The highlight of this sunrise walk was this large sandcastle on the beach in front of a condominium, the Hilton is to the left. Lori Wilson Park is out of sight to the left. A great feature of the park, for us since the International Palms were we stayed is next to it to the north, was the park life guards.
So, we approached this sandcastle from the north. It survived the high tide to a new day, obviously it required time and resources to build. The day before was a big beach day. Wednesday was a brilliant, summer-like day for the first of March.
A little closer, the footsteps inside the first moat are interesting.
Pam next to the castle provides scale
Here is the central pyramid. I enjoy the dawn light on the grasses. That is a sea gull feather on the apex.
Decorative sea shell band facing the ocean.
The destiny of all our human conceits. Impermanence is part of the beauty of sand castles.
Images of Newlyweds on the beach
With grandchildren in the Miami Area and a sister in Daytona Beach, Florida was on my mind this morning and memories of this beautiful experience on Cocoa Beach came to mind. After an eventful day touring the NASA launch control center, Pam and I took an evening walk during the golden hour, me with camera in hand.
Full in expectation of catching the passing scene with lots of shot I set to full size jpeg mode using a Sony Alpha 700 dslr with a DT 18-200mm f3.5-6.3 lens. The light was exceptional, so I did not expect much post production work.
My first impression was of the line of cruise ships heading south from Port Canaveral, the starboard side lit perfectly behind human denizens of the Cocoa Beach shore, in full enjoyment mode. A synergy of the images struck me. I took a few experimental shots then, as we progressed down the beach front this unusual tableau came into view.
Pulling back the focal length a bit the reason for the bride and groom on the beach is clear.
The session proceeded smoothly and professionally, it was a pleasure to watch. I felt no compunction for capturing these private moments on a public beach, the transcendence of the images reflect well on all participants.

The Sun’s Progress
Two minutes after capturing the last light on Concon Point, see “Valparaiso Departure II”, turning the camera 180 degrees, to the south, looking along the Chilean coast, to capture birds on the wing headed toward shore at day’s end.
Remembering other times,
waiting for darkness
with a sky map, studying it to make sense of the stars.
How far? How large?
Light from our star, eight minutes old,
grazed the earth’s rim the breath of a moth wing ago.
Connect the dots, stories of heroes, monsters.
Our star, as we know it now
Progress, an illusion to be understood
No less mysterious for that
Look back to the sheltering headland of Valparaiso, glowing.
crack of dawn
In this post we start the day of my posting “Family Trek“, July 19, 2008, when, well before the sun rose at 6:23 am Mountain Daylight Time (the Navajo Reservation observes daylight savings, the rest of Arizona does not), Pam and I were at the Spider Rock Overlook.
Most visitors to the canyon make use of a system of roads and parking lots next to strategic views. There is the White House Overlook we visited our first day, July 18, to hike from the trailhead into the canyon. There are also, on the south side of the canyon:
While getting ready I scoped out the location for interesting visual tropes. Utah Junipers are exceptionally hardy shrubs, stressed individual plants grow into compelling forms shaped by hardship. As the sun rose, this specimen emerged from the gloom and caught the first sun rays.
The Flag Forms
Here is a postscript for my retrospective diary of the day I created my print “Ocotillo Sunset.” You can visit “Ocotillo Sunset” in my Online Gallery by clicking on any photograph .
In near total darkness, the last sunlight only enough for the far western sky, these are the last shots of this series.
The final result of the day’s work, “Ocotillo Sunset.”
The Flag Forms
The penultimate posting of my retrospective diary of the day I created my print “Octillo Sunset.” You can see a large version of “Ocotillo Sunset” by clicking on any of my blog photographs.
Then, for reasons I can only speculate about, a spectacular shape came together in the clouds. In the following photograph I have yet to recognize, to see, this cloud sculpture. Do you see part of “Ocotillo Sunset” coming into shape? As far as I remember, at the time I had only a dim realization of what was forming in my view finder and in front of me.
Then, I changed camera orientation and shifted the view a few degrees to the left and there it was: a coherent shape of something. Here it is in full, untethered.
The final result of the day’s work, “Ocotillo Sunset.”
Shooting As The World Turns
This is a retrospective diary of the day I created my print “Ocotillo Sunset.” You can see a large version of “Ocotillo Sunset” by clicking on any of my blog photographs.
In Part 5, we enter the final phase of this day’s work with darkening of the land while in the sky sunlight reflects off high clouds. The length of this moment when twilight is over, just before night falls, varies with latitude and time of year. Near the poles (high latitude) this light can last for days while here, at about 32 degrees north, it is less than 15 minutes. As I wrote in Part 4, after this light, the desert is absolutely dark. This is why I chose to set up by the roadside.
In the following two photographs I experimented with camera placement and foreground elements. Starting in Part 4 I became aware of Ocotillo branches, using them for the effect of reaching for and, here, anchoring the clouds.
These earth-bound Ocotillo branches lead me to the darkened earth. How much to include in the shot? I searched for a balance between the vastness and complete blackness and needed a point of interest. Time was running out.
