Rare sunset solar eclipse Thursday

October 22nd, 2014 at 7:10 pm by under Weather

Sunsets are always pretty.  Thursday evening’s sunset could be out of this world. The setting sun across eastern parts of the USA will be red, beautiful and … crescent-shaped.

“It’s a partial solar eclipse,” explains longtime NASA eclipse expert Fred Espenak.  In other words, the New Moon is going to ‘take a bite’ out of the sun.

In the Austin and Central Texas area, the eclipse will begin around 4:55 p.m., reach its maximum (25% obscuration) at 5:56 p.m., and end at sunset.

A total eclipse is when the Moon passes directly in front of the sun, completely hiding the solar disk and allowing the sun’s ghostly corona to spring into view. A partial eclipse is when the Moon passes in front of the sun, off-center, with a fraction of the bright disk remaining uncovered.

The partial eclipse of Oct. 23rd will be visible from all of the United States except Hawaii and New England.  Coverage ranges from 12% in Florida to nearly 70% in Alaska.  Weather permitting, almost everyone in North America will be able to see the crescent.

The eclipse will be especially beautiful in eastern parts of the USA, where the Moon and sun line up at the end of the day, transforming the usual sunset into something weird and wonderful.

“Observers in the Central Time zone have the best view because the eclipse is in its maximum phase at sunset,” says Espenak. “They will see a fiery crescent sinking below the horizon, dimmed to human visibility by low-hanging clouds and mist”.

Warning: Don’t stare. Even at maximum eclipse, a sliver of sun peeking out from behind the Moon can still cause pain and eye damage. Direct viewing should only be attempted with the aid of a safe solar filter.

During the eclipse, don’t forget to look at the ground. Beneath a leafy tree, you might be surprised to find hundreds of crescent-shaped sunbeams dappling the grass. Overlapping leaves create a myriad of natural little pinhole cameras, each one casting an image of the crescent-sun onto the ground beneath the canopy. When the eclipsed sun approaches the horizon, look for the same images cast on walls or fences behind the trees.

Here’s another trick: Criss-cross your fingers waffle-style and let the sun shine through the matrix of holes. You can cast crescent suns on sidewalks, driveways, friends, cats and dogs—you name it. Unlike a total eclipse, which lasts no more than a few minutes while the sun and Moon are perfectly aligned, the partial eclipse will goes on for more than an hour, plenty of time for this kind of shadow play.

A partial eclipse may not be total, but it is totally fun.

See for yourself on Oct. 23rd.  The action begins at approximately 6 pm on the east coast, and 2 pm on the west coast.  Check NASA’s Eclipse Home Page for viewing times near your hometown.

Orionid meteor shower early Tuesday morning

October 20th, 2014 at 3:58 pm by under Weather

(Courtesy: Earthsky.org)

By

In 2014, the annual Orionid meteor shower is expected to rain down the greatest number of meteors before dawn on October 21, perhaps as many as 25 meteors per hour. But the hours between midnight and dawn on the mornings of October 20 and 22 may offer a decent sprinkling of meteors as well.

The Orionids radiate from a point near the upraised Club of the constellation Orion the Hunter.  The bright star near the radiant point is Betelgeuse.

The Orionids radiate from a point near the upraised Club of the constellation Orion the Hunter. The bright star near the radiant point is Betelgeuse.

What are the prospects for this year’s Orionid shower? In short, the prospects are good because there’s little or no moon to wash out the meteors this year. Find a dark sky for the 2014 Orionids, lie down on a reclining lawn chair in comfort and look up! Give yourself at least an hour of watching time for meteors tend to come in spurts, and are interspersed by lulls. Remember, also, that it takes about twenty minutes for your eyes to adapt to the dark.

When is the best time to watch for the Orionids? As with most (but not all) meteor showers, the best time to watch the Orionid shower is between the hours of midnight and dawn. The Orionids don’t really begin to streak the nighttime sky until late evening, when the magnificent constellation Orion ascends over the eastern horizon. After their radiant point rises, you see many more meteors, and as the radiant rises higher in the sky throughout the night, the meteors will increase in number. That’s why the wee hours before dawn are usually the best.

Where do I look in the sky to see the Orionids? Yes, meteors in annual showers are named for the point in our sky from which they appear to radiate. The radiant point for the Orionids is in the direction of the famous constellation Orion the Hunter. Hence the name Orionids.

If you trace the paths of these Orionid meteors backward, they seem to come from the Club of Orion. You might know Orion’s bright, ruddy star Betelgeuse. The radiant is north of Betelgeuse.

But you don’t need to know this constellation to see the meteors. The meteors often don’t become visible until they are 30 degrees or so from their radiant point – and remember, they are streaking out from the radiant in all directions. So the meteors will appear in all parts of the sky.

That’s why it’s best to find a wide-open viewing area than to look in any particular direction. Sometimes friends like to watch together, facing different directions. When somebody sees one, they can call out “Meteor!”

How many Orionid meteors will I see? The word shower might give you the idea of a rain shower. But few meteor showers resemble showers of rain. The Orionids are a relatively modest shower, offering about 10 to 25 meteors per hour.

Meteor showers are more subtle than rain showers, and the Orionid shower isn’t as rich a meteor shower as, for example, the Perseids in August or the Geminids in December. But the dark skies make this year’s orionid meteor shower worth watching!

Orionid meteors are known to be fast and usually on the faint side. But the Orionids can sometimes surprise you with an exceptionally bright meteor – one that would be visible, even in a light-polluted city – that might break up into fragments.

For me … even one meteor can be a thrill. But you might want to observe for an hour or more, and in that case the trick is to find a place to observe in the country. Bring along a blanket or lawn chair and lie back comfortably while gazing upward.

This is the famous Comet Halley. Orionid meteors are debris left behind in its orbit.

What are meteors, anyway? Meteors are fancifully called shooting stars. They aren’t really stars. They’re space debris burning up in the Earth’s atmosphere.

The Orionid meteors are debris left behind by Comet Halley. The object at left isn’t a meteor. It’s that most famous of all comets – Comet Halley – which last visited Earth in 1986. This comet leaves debris in its wake that strikes Earth’s atmosphere most fully around October 20-22, while Earth intersects the comet’s orbit, as it does every year at this time.

Particles shed by the comet slam into our upper atmosphere, where they vaporize at some 100 kilometers – 60 miles – above the Earth’s surface.

The Orionids are extremely fast meteors, plummeting into the Earth’s atmosphere at about 66 kilometers – 41 miles – per second. Maybe half of the Orionid meteors leave persistent trains – ionized gas trails that last for a few seconds after the meteor itself has gone.

Bottom line: In 2014, the Orionid meteor shower is expected to rain down its greatest number of meteors on the morning of October 21. The day before or after might feature meteors, too. Fortunately, in 2014, the thin lunar crescent rising shortly before sunrise won’t intrude on this year’s Orionid meteor shower!


LEDs are a bright idea whose time has come

October 20th, 2014 at 1:23 pm by under Weather

(Climate Central) The day the Nobel committee began announcing its 2014 winners earlier this week, National Geographic published a list of Nobel should-have-beens. Dan Vergano’s contribution—Thomas Edison for the lightbulb—proved prescient. One day later, a Nobel for physics was finally awarded for the lightbulb. Unfortunately for the Wizard of Menlo Park, it didn’t go to Edison. The winners were Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura for their work on blue light-emitting diodes, or LEDs.

LEDs represent a huge increase in the efficiency of lighting.

Edison was still a genius, and his inventions did change the world, but he’s not exactly an environmental hero. Only about 2 percent of the energy that flows through the filament of an incandescent bulb actually generates light. Edison’s invention is a much better heater than a light source.

LEDs are a dramatic improvement. The most cutting edge claim to be 15 times more efficient than the incandescent bulb and four times more efficient than compact fluorescents (the squiggly ones), which now appear to be little more than a transitional technology. On a global scale, the energy savings from a worldwide switch to LEDs could be massive. In 1997, when incandescent bulbs still ruled the night, Evan Mills of Lawrence Berkeley National Laboratory estimated that lighting resulted in the emission of 1,775 million metric tons of carbon dioxide equivalents. If, at that moment, we could have immediately replaced all of the world’s incandescent bulbs with LEDs, the greenhouse gas savings would have been like taking 300 million cars off the road.

In real life, the changeover from incandescent to compact fluorescent to LED bulbs has had a less dramatic impact, for a variety of reasons. The most depressing candidate is known as the “rebound effect,” as Brad Plumer points out at Vox. The theory goes that when lighting (or any technology) becomes more efficient, it gets cheaper. When something gets cheaper, people use more of it. The rebound effect, however, is a hotly disputed phenomenon. Physicist David Goldstein and his colleagues at NRDC (which publishes OnEarth) argue that the rebound effect is at best negligible on a societal scale. Their data shows that people use only a tiny fraction of their energy savings to buy more lighting (or heating or refrigeration or whatever the more efficient technology may be). “Policies and consumer preferences are steadily pushing in the opposite direction—saving more energy, not less,” Goldstein writes.

Another challenge with LEDs, known as droop, has troubled physicists for years. As you increase the current flowing through an LED, the efficiency plummets from 300 lumens per watt of power down below 100 lumens, which isn’t much better than a compact fluorescent bulb (which costs a small fraction of the LED’s current price tag). A few people, including recently minted Nobel laureate Nakamura, have proposed explanations for what causes droop, but no one is entirely certain. Once physicists find the answer, it will still take engineers years to design a solution. Until then, producing bright light with low amounts of energy requires lots and lots of small LEDs stacked together, which is a problem from both a cost and an engineering standpoint.

Approximately 19 percent of the world’s population lacks access to electricity. LEDs could eventually offer a cheap, low-carbon light.

Fortunately, the LED light may play a role in training the scientist who will eventually solve this problem. Approximately 19 percent of the world’s population lacks access to electricity, and there are surely many geniuses among them. The LED’s tiny energy demands make it possible for off-grid communities to store enough solar power in low-cost batteries (see “India Calling”) to provide light after sunset.

Why does that matter? My father-in-law grew up in a small village in India. When the sun went down, he had to stop studying, because his family couldn’t provide enough light to read. He still managed to earn a Ph.D. in chemical engineering, but I often wonder how many kids like him were held back by darkness — an absurd obstacle to academic achievement in the modern world. Maybe one day the Nobel Prize will go to a child who can thank today’s winners for all those late nights spent studying under their creation.

El Niño not here yet, but still expected

October 9th, 2014 at 2:54 pm by under Weather

El Nino developing temp anomaliesEl Niño Status: El Niño Watch

Synopsis: El Niño is favored to begin in the next 1-2 months and last into the Northern Hemisphere spring 2015.

During September 2014, above-average sea surface temperatures (SST) continued across much of the equatorial Pacific (Fig. 1). The weekly Niño indices were relatively unchanged from the beginning of the month, with values ranging from +0.3oC (Niño-3.4) to +1.1oC (Niño-1+2) at the end of the month (Fig. 2). The change in subsurface heat content anomalies (averaged between 180o-100oW) was also minimal (Fig. 3) due to the persistence of above-average temperatures at depth across the central and eastern Pacific (Fig. 4). Equatorial low-level winds were largely near average for the month, though brief periods of westerly wind anomalies continue to arise. Upper-level winds were also close to average for the month. The Southern Oscillation Index has remained negative, and rainfall was near average around the Date Line, with a mix of positive and negative anomalies over Indonesia and Papua New Guinea (Fig. 5). The lack of coherent atmospheric and oceanic features indicates the continuation of ENSO-neutral.

Most models predict El Niño to develop during October-December 2014 and to continue into early 2015 (Fig. 6). The consensus of forecasters indicates a 2-in-3 chance of El Niño during the November 2014 – January 2015 season. This El Niño will likely remain weak (3-month values of the Niño-3.4 index between 0.5oC and 0.9oC) throughout its duration. In summary, El Niño is favored to begin in the next 1-2 months and last into the Northern Hemisphere spring 2015 (click CPC/IRI consensus forecast for the chance of each outcome).

This discussion is a consolidated effort of the National Oceanic and Atmospheric Administration (NOAA), NOAA’s National Weather Service, and their funded institutions. Oceanic and atmospheric conditions are updated weekly on the Climate Prediction Center web site (El Niño/La Niña Current Conditions and Expert Discussions). Forecasts are also updated monthly in the Forecast Forum of CPC’s Climate Diagnostics Bulletin. Additional perspectives and analysis are also available in an ENSO blog. The next ENSO Diagnostics Discussion is scheduled for 6 November 2014.

Double-crested and pied-billed

Double-crested Cormorants begin arriving in substantial numbers throughout October and soon will be a familiar sight as they roost along the south shore of Lady Bird Lake in the cypress trees. Cormorants are large, gangly black birds with orange faces, long necks and long hooked bills. You can sometimes see them sitting with their wings spread out awkwardly to dry.

You also may see newly arrived Pied-billed Grebes on the lakes and small ponds of Central Texas. These very small water birds are common in most of the U.S. year-round, but they gather in larger flocks come winter (which, for birds, is approaching fast, even though we humans might not think so). These grebes are brown and compact, with very short bills and no tail to speak of. They are noticeably smaller than other birds out on the lake, with heads that are large relative to their bodies.

They do lots of diving and can actually control their buoyancy, sinking into the water like submarines. In spring and summer, the bird’s bill is pied — white with a black stripe — but in winter is a yellowish brown.

Monthly Meeting — Where to Bird in Central Texas
6:30 p.m. Thursday, Oct. 16, Hyde Park Christian Church, 610 E 45th St.
