Late Winter, on the cusp of Spring, I arrived at the Cornell Experimental farm before sunrise.
There I set up a Kodak DSC Pro SLR/c with a Canon EF 50 mm f/1.4 USM lens all mounted on a very stable Manfrotto Studio Aluminum Tripod Model 475 and Hydrostatic Ball Head. From this 15 exposures were obtained. Photoshop CS6 HDR combined the 15 into this perfected image. Cornell Thompson Experimental Farm, Town of Dryden, Tompkins County, New York

No, the Manatee mailbox on Atlantic Avenue is NOT the whale sighted….more of that later. February 3rd 2022 dawned with scattered clouds to fracture sunbeams.
Walking south I made the 2+ mile point where, up from the beach on South Atlantic Avenue, is a memorable facade.
Also exotic schefflera, paths to the beach through Sea Grapes.
Looking back to the Sea Grapes path from the beach
February is the time for Right Whale sightings on the Florida Atlantic Coast. On the beach, near the blue dot on the following map, were lines of people facing the ocean, some with binoculars and cameras with long lenses.
About 500 feet out, beyond where the wave roll begins, a person sat on a paddle board looking to my right. In the following IPhone videos an occasional black hump, roiling water, a flipper and the signature spout are visible. It is too far for identification, I call it a Right Whale from their reputation for visiting these shores in late January/February.
An hour later, I left the beach at South 4th Street to capture the following local color.

Booking our February/March 2016 passage on the Oceania Regatta from Lima, Peru to Buenos Aires, Argentina we started early, Spring 2017. We made two excellent choices: a stateroom with balcony on the port side. Waking each morning we were treated to views of the shoreline. On the morning of February 15, 2016 as we sailed the Chacao Channel toward Puerto Montt I was up 4:15 am before the sun rose to photograph our approach to the city.
I knew a classic 8,701 foot high stratovolcano topped with glaciers, named Orsorno, was out there and, amazingly, appeared on the horizon, seventy five miles distant to the northeast outlined by the gathering dawn. The sky was just brightening from total darkness at this time.
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.
Edge of Civil Twilight: dark clouds soon to take light
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.
Civil Twilight at the edge of sunrise
Sunrise has passed in the following photographs, obscured by clouds and making for a great light show. Enjoy!!

When Pam read my post “Black Skimmers Feeding” she asked, “Where is the photo of resting Skimmers?”
To answer her question, I looked through Cocoa Beach photographs and discovered I did NOT capture the Skimmers resting. Instead, here are a related species, the Royal Tern (scientific name: Thalasseus maximus), whose behavior is similar in that it exclusively feeds from the water. There was a wind that morning and these individuals face into it. These birds are, from a human point of view, well behaved, unlike the opportunistic gull.
I searched around the web for identification of this gull without success.
It dines on a dead fish washed up by the surf. In my previous posting I used the word “grifting” to describe gull behavior, again this is from the human point of view. Gulls are notorious for stealing food from unwary beach goers, brazening walking over to unguarded chips (any kind), for instance, grabbing them and flying off. If the chip stash is large, this sets off a nasty feeding frenzy when tens of gulls swoop in and grab.
Here is a series of photographs, demonstrating this behavior.
The planet we call Venus has ancient associations with fertility goddesses. The link has persisted at least from the 1600 century B.C. inscribed on Sumerian cuneiform tablets. Three thousand years later the Italian artist Botticelli created in tempura paint on canvas the image of Venus rising from the sea, as the planet Venus does today.

Venus Rising
Here is Venus rising from the sea at dawn January 2022, at its brightest and most beautiful. Some mistake this new light in the east for airplane lights; the bright disk of Venus is 25 times brighter than Sirius, enough to cast shadows at night. As Venus proceeds in its orbit, the planet alternately sets after the sun and rises before it, seemingly appearing new each time.
This February I caught a newly risen Venus in this IPhone 7 video, reflected in the waves. It seemed to be a flashing headlight on the beach, the Venus reflection came and went with the passing waves. Venus is the upper, the reflection is beneath. Use the lower right control for the full view.
Looking from his window June 1889, Vincent VanGogh included Venus in his “Starry Night” painting, seen to the right of the Cypress tree.

Here is a closer view of Venus last January, the planet disk is apparent, unlike even the closest stars, Venus is seen as a whole object. Click on image for a full view.
Venus and Mars
Venus and Mars shared 2022’s pre-dawn winter sky. Click on the first image for a full-size view. Mars is seen above the palm tree stump, on the right. In this photograph, from early February, Venus and Mar apparently moved closer. The closeness is an illusion, the planets are millions of miles apart, on either side of Earth’s orbit. Click on the photograph for a full-size view, Mars can just be made out to the right and above Venus.

This crop clearly shows the brightness of Venus compared to Mars.
