APOD: Solstice: Sunrises Around the Year (2020 Dec 21)

Post by APOD Robot » Mon Dec 21, 2020 5:05 am

Image Solstice: Sunrises Around the Year

Explanation: Does the Sun always rise in the same direction? No. As the months change, the direction toward the rising Sun changes, too. The featured image shows the direction of sunrise every month during 2019 as seen from near the city of Amman, Jordan. The camera in the image is always facing due east, with north toward the left and south toward the right. Although the Sun always rises in the east in general, it rises furthest to the south of east on the December solstice, and furthest north of east on the June solstice. Today is the December solstice, the day of least sunlight in the Northern Hemisphere and of most sunlight in the Southern Hemisphere. In many countries, the December Solstice is considered an official change in season: for example the first day of winter in the North. Solar heating and stored energy in the Earth's surface and atmosphere are near their lowest during winter, making the winter months usually the coldest of the year. On the brighter side, in the north, daylight hours will now increase every day from until June.

The URL of the main image, the one you get when you click on the home page image.

The source page from the imager suggests the pictures range from December solstice 2018 to December solstice 2019.

It looks like a vertical sine wave!
The 2017 presumably refers to the resolution of the image. 2017 × 2911 pixels.

Actually I think its a Cosine wave,
(or maybe its just a bunch of photon particles).

<<Creme Puff (August 3, 1967 – August 6, 2005) was a domestic cat, owned by Jake Perry of Austin, Texas. She was the oldest cat ever recorded, according to the 2010 edition of Guinness World Records, when she died aged 38 years and 3 days.

Creme Puff's diet consisted of dry cat food supplemented with broccoli, eggs, turkey bacon, and coffee with cream; it was a diet her owner, Jake Perry, held to be key to her longevity. Every two days, Creme Puff received "an eyedropper full of red wine" which Perry said "[circulated] the arteries". Perry also kept Creme Puff active within the home, turning his garage into a movie theater which played nature documentaries for his cats. Wooden steps were built into the walls of Perry's home for the cats to climb on, and Perry had built a screened enclosure in his backyard for his pets, including Creme Puff, to enjoy the outdoors.

The life expectancy of a cat that is living indoors is typically about 16.9 years, while the life expectancy of one living outdoors is 5.6 years. In one study of cat mortality, the most frequent causes were trauma (12.2%), renal disorder (12.1%), non-specific illness (11.2%), neoplasia (10.8%) and mass lesion disorders (10.2%). Female cats have been evidenced to outlive male cats, while neutered cats and crossbred cats have been evidenced to outlive entire and purebred cats, respectively. It has also been found that the greater a cat's weight, the lower its life expectancy on average. An accurate equation often used by veterinarians to predict cat years is 4x + 16, (x being the chronological age of the cat) which works for cats who are two years of age or older. [Ergo: Creme Puff died at age 168!]>>
