APOD: Moon Shadow Sequence (2012 Nov 16)

Post by APOD Robot » Fri Nov 16, 2012 5:06 am

Image Moon Shadow Sequence

Explanation: On the morning of November 14, the Moon's umbral shadow tracked across northern Australia before heading into the southern Pacific. Captured from a hilltop some 30 miles west of the outback town of Mount Carbine, Queensland, a series of exposures follows the progress of the total solar eclipse in this dramatic composite image. The sequence begins near the horizon. The Moon steadily encroaches on the reddened face of the Sun, rising as the eclipse progresses. At the total phase, lasting about 2 minutes for that location, an otherwise faint solar corona shimmers around the eclipsed disk. Recorded during totality, the background exposure shows a still sunlit sky near the horizon, just beyond a sky darkened by the shadow of the Moon.

It would have been nice if we could have gotten a few more moon-beads showing on the solar-eclipse necklace. We don't get to see to much of that kind of jewelry hanging around here.

Numerous APODs have solar eclipses, star fields and galaxies, and same old things - they have become very common, routine, and perhaps repeatatively boring?

No they have not become boring.

Doesn't anyone proofread these blurbs?

Thanks for the note; TPTB have been informed.

And no, no one proofreads these except those who write them. It's not as though there's a huge APOD staff, you know; just two astrophysicists squeezing the production of APODs every.single.day. into their very busy lives.

I proofread them sometimes but I don't always catch APODs before they're published. That, and it's not very fun to do because most of them are just fine. You never know when a mistake will appear...

If one could somehow know when a mistake would appear, there'd be no need for proofreaders...

Fair enough. But I secretly enjoyed proofreading my fellow students' papers in English classes because I got to draw lots of red marks all over them. Looking through them in APODs is no fun because it's more like a needle in a haystack and it spoils the APOD for the next day, too.

http://en.wikipedia.org/wiki/Wolf_Creek_%28film%29 wrote: <<Wolf Creek is a 2005 independent Australian horror film [that] revolves around three backpackers who find themselves held captive by a serial killer in the Australian outback. Wolf Creek was marketed as being "based on true events."

One particular location that was used during the shooting of the travellers' drive to Wolf Creek had not seen rainfall in over six years – however, once the crew arrived and shooting proceeded, it rained for three continuous days, forcing the writer, director and actors to incorporate the highly unexpected rainfall into the script. According to Greg McLean, the fact that it was raining and gloomy in an otherwise dry, sunny desert area gave the sequences a feel of "menace".

Two British tourists, Liz Hunter (Cassandra Magrath) and Kristy Earl (Kestie Morassi) are backpacking across the country with Ben Mitchell (Nathan Phillips), an Australian friend and contrarian. Currently in Broome, Western Australia, they constantly get drunk at wild, extravagant pool parties and sleep rough together on the beach. Ben buys a dilapidated Ford XD Falcon to facilitate their road journey from Broome to Cairns, Queensland via the Great Northern Highway.

After stopping at Halls Creek for the night, the trio make another stop at Wolf Creek National Park, which contains a giant crater formed by a 50,000-ton meteorite. Wolf Creek is set in a real location; however, the actual meteorite crater location is called "Wolfe Creek", and is located in northern Western Australia. It is the second largest meteorite crater in the world from which meteorite fragments have been recovered. Wolf Creek was filmed almost entirely in South Australia; however the aerial shots of the crater in the film show the genuine Wolfe Creek crater.

While exploring the crater, Ben and Liz kiss, after various hints from Kristy. Hours later, upon returning to their car, the group discovers their watches have all suddenly broken and the car won't start. After dark, a Crocodile Dundee-styled man named Mick Taylor (John Jarratt) comes upon them and offers to tow them to his camp to repair the car. After initial hesitation, the group allows Mick to take them to his place, an abandoned mining site several hours south of Wolf Creek. Mick regales them with tall stories of his past while making a show of fixing the car. His manner unsettles Liz and Kristy, although Ben is less concerned. While they sit around a fire, Mick gives the tourists drugged water which he describes as "rainwater from the top end". The water causes the tourists to eventually fall into unconsciousness.
The rock quarry where Mick's mining site is located was the site of a real-life murder, which stirred up controversy from the local residents who mistook the film as being based on that crime. According to director McLean and others, John Jarratt went to extremes in preparing for his role as Mick, in a bid to emulate, as close as possible, the real-life serial killer Ivan Milat: he spent significant time alone in the isolated outback and went for weeks without showering. The sign on the front gate of Mick's mining site reads "Navithalim Mining Co." Navi & thalim spelt backwards reads: Ivan Milaht, evidently referencing Ivan Milat.>>

I noticed that the sun appears to be tracing a curved path. I wonder if that is due to the use of a wide-angle lens? Or was the camera moved during totality? The path prior to totality seems somewhat straight, and after totality also somewhat straight, although less-so, so that in replacing the camera after totality the orientation was slightly different? Perhaps it is my monitor?

I love seeing how the morning ecliptic goes from lower right toward upper left in the southern hemisphere, the opposite of what I'm used to seeing in the northern hemisphere. And this picture shows us why it's called the ecliptic!

Just four years, nine months, and five days until the next total solar eclipse visible in the continental Untied States. (*)

Great picture.....where's the Koala??? Do you think Kangaroo notice an Eclipse???

Note the Aborigine myth of solar eclipses....got to remember this one for the right time....hmmmm...

From Wikipedia...Australian Aboriginal Astronomy... the worlds oldest astronomers...
"Eclipses

The Warlpiri people explain a solar eclipse as being the Sun-woman being hidden by the Moon-man as he makes love to her.[5] This explanation is shared by other groups, such as the Wirangu.[9] On the other hand, a lunar eclipse is caused when the Moon-man is pursued and threatened by the Sun-woman.[5][10]

In the Kuringai National Park there are a number of engravings showing a crescent shape, with sharp horns pointing down, and below it a drawing of a man in front of a woman. While the crescent shape has been assumed by most researchers to represent a boomerang, some argue that it is more easily interpreted as a solar eclipse, with the mythical man-and-woman explanation depicted below it."

Very nicely composed and executed view. I like seeing the multiple images as the sun rises. Checked out Ben Cooper's website too; some really stunning photography! . . well worth a look.

Isn't this coherent sequence of photographs of the recent Australian total Sun eclipse pertinent as proof of the mythical nature of the so called Nibiru system that is allegedly, actually, approaching —precisely from the southern hemisphere— our sun and inner solar system planets?

Only if you assume that Nibiru is a naked eye object, in which case it would certainly have been apparent in southern hemisphere images a few months ago, when it wasn't near the apparent position of the Sun. There are much more compelling reasons to explain the non-existence of Niburu than this image.

I don't know what I was thinking. Of course the path is a circle. I'm not used to thinking of the sun and the moon tracing a circle across the sky. Stars yes, Sun and Moon No. (I know, the Sun is a star too). But they only rarely appear in time exposures and are rarely close to the poles, and so their paths appear linear until you think about them this way. At least they do for me. Until now. Duh! Thanks APOD.
