ปล.ดูจุดดับ 1319 ไว้มันขยายใหญ่ และกระจายด้วย ตอนนี้มีแนวตรงกับโลก แถมยังมีแนวตรงกับประเทศไทย (ทางภาคใต้ของไทย)

 

600 MYSTERIES IN THE NIGHT SKY: The Fermi Gamma-ray Space Telescope recently produced a map of the night sky. Out of 1873 new sources, nearly 600 were complete mysteries. In today's story from Science@NASA, researchers speculate on the nature of the mystery objects--including the possibility that they are made of dark matter.

 

จุดดับที่ active: กลุ่ม จุดดับ 1319 ประกอบด้วยหลายๆ จุดดับรวมๆ กัน หลายๆ กลุ่มฝูงมดทหารมารวมกันเป็นกลุ่มๆ และกลุ่มนี้ก็ขยายขึ้นเรื่อยๆ ในสุดสัปดาห์ที่ผ่านมา กลุ่มของจุดดับเพิ่มขึ้นเป็นสามเท่าเหมือนที่รูปด้านล่างแสดงให้เห็น

ตามที่จุดดับ AR1319 ขยาย ตัว และทำให้ความซับซ้อนของสนามแม่เหล็กเพิ่มขึ้นด้วย เพดานแม่เหล็กของจุดดับตอนนี้ไม่เสถียรเลย และก็ซ่อนพลังงานที่จะก่อให้เกิดการระเบิดของ M-Class. NOAA พยากรณ์ว่าโอกาสที่จะเกิดการระเบิดมีประมาณ 40% ใน 24 ชั่วโมงข้างหน้า

ACTIVE SUNSPOT: Active region 1319 contains so many individual sunspots that some observers have likened it to a swarm of army ants. The swarm is growing. Over the weekend, the sunspot group's total area nearly tripled as shown in this movie from the Solar Dynamics Observatory:




As AR1319 has grown, the complexity of its magnetic field has increased as well. The sunspot's magnetic canopy is now unstable and harbors energy for strong M-class solar flares. NOAA forecasters estimate a 40% chance of such an eruption during the next 24 hours. Solar flare alerts: text, voice.

Comet Storm in a Nearby Star System

Oct. 19, 2011: NASA's Spitzer Space Telescope has detected signs of icy bodies raining down in an alien solar system. The downpour resembles our own solar system several billion years ago during a period known as the "Late Heavy Bombardment," which may have brought water and other life-forming ingredients to Earth.



"We believe we have direct evidence for an ongoing Late Heavy Bombardment in the nearby star system Eta Corvi, occurring about the same time as in our solar system," said Carey Lisse, senior research scientist at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., and lead author of a paper detailing the findings to appear in the Astrophysical Journal.

During the Late Heavy Bombardment, comets and other frosty objects from the outer solar system pummeled the inner planets. The barrage scarred our Moon and produced large amounts of dust.


Spitzer has spotted a band of dust around Eta Corvi that strongly matches the contents of an obliterated giant comet, probably destroyed by a collision with a planet or some other large body. The dust is located close enough to Eta Corvi that Earth-like worlds could exist in the collision zone, suggesting that planets like our own might be involved. The Eta Corvi system is approximately one billion years old, which researchers think is about the right age for such a hailstorm.


Astronomers used Spitzer's infrared detectors to analyze the light coming from the dust around Eta Corvi. Curiously, the light signature emitted by the dust around Eta Corvi resembles the Almahata Sitta meteorite, which fell to Earth in fragments across Sudan in 2008. The similarities between the meteorite and the object obliterated in Eta Corvi imply a common birthplace in their respective solar systems.


A second, more massive ring of colder dust located at the far edge of the Eta Corvi system seems like the proper environment for a reservoir of cometary bodies. This bright ring, discovered in 2005, matches the size of a similar region in our own solar system, known as the Kuiper Belt, where icy and rocky leftovers from planet formation linger. The comets of Eta Corvi and the Almahata Sitta meteorite may have each originated in the Kuiper Belts of their respective star systems.


About 4 billion years ago, not long after our solar system formed, scientists think the Kuiper Belt was disturbed by a migration of Jupiter and Saturn. This jarring shift in the solar system's gravitational balance scattered the icy bodies in the Kuiper Belt, flinging the vast majority into interstellar space and producing cold dust in the belt. Some Kuiper Belt objects, however, were set on inward paths that crossed the orbits of Earth and other rocky planets.


The resulting bombardment of comets lasted until 3.8 billion years ago. After comets hit the side of the Moon that faces Earth, magma seeped out of the lunar crust, eventually cooling into dark "seas." Everyone has seen them: Those seas form the distinctive face of the "Man in the Moon." Comets also struck Earth or incinerated in the atmosphere, and are thought to have deposited water and carbon on our planet.



This period of impacts might have helped life form by delivering its crucial ingredients.


"We think the Eta Corvi system should be studied in detail to learn more about the rain of impacting comets and other objects that may have started life on our own planet," Lisse said.

ROSAT DECAY UPDATE: The doomed ROSAT X-ray space telescope continues to descend toward Earth. Multiple experts agree that re-entry should occur on Oct. 23rd, with most favoring the early hours of the day. With uncertainties exceeding 8 hours, however, it is still impossible to say exactly where ROSAT will disintegrate.


​

Observers say ROSAT is bright and easy to see, but photographers are having a hard time catching it. Dewey Vanderhoff tracked it over Cody, Wyoming, on Oct. 18th: "It was easily the fastest-moving satellite I have ever seen, being in such a low orbit and accelerating towards its doom. I barely got off a 'shotgun' 2-second exposure as ROSAT raced between Pegasus and Pisces (image)."​

On Oct. 16th, astrophotographer Thierry Legault trained his 14-inch telescope on the observatory, and this is what he saw:​

​

A video of the flyby may be found on Legault's web site. "The satellite looks very steady," he says, "there was no sign of tumbling or flares. Visually, ROSAT was crossing the sky so fast! I hope that it will give a nice fireworks over my place when it re-enters."

​

Until then, sky watchers should be alert for a fast-moving light in the night sky. To catch ROSAT, check Spaceweather's Satellite Tracker for local flyby times. You can also turn your smartphone into a field-tested ROSAT tracker.

Weekend Meteor Shower

Oct. 20, 2011: Earth is about to pass through a stream of debris from Halley's comet, source of the annual Orionid meteor shower. Forecasters expect more than 15 meteors per hour to fly across the sky on Saturday morning, Oct. 22nd, when the shower peaks.


Orionids are most easily seen during the dark hours before sunrise. Twilight Orionids, however, are the most beautiful of all.

"Although this isn't the biggest meteor shower of the year, it's definitely worth waking up for," says Bill Cooke of the NASA Meteoroid Environment Office. "The setting is dynamite."

Orionids are framed by some of the brightest and most beautiful constellations in the night sky. The meteors emerge from mighty Orion, the shower's glittering namesake. From there they streak through Taurus the Bull, the twins of Gemini, Leo the Lion, and Canis Major--home to Sirius, the most brilliant star of all.

This year, the Moon and Mars are part of the show. They'll form two vertices of a celestial triangle in the eastern sky on Saturday morning while the shower is most active; Regulus is the third vertex. Blue Regulus and red Mars are both approximately of 1st magnitude, so they are easy to see alongside the 35% crescent Moon. Many Orionids will be diving through the triangle in the hours before dawn.
Cooke's team at the Meteoroid Environment Office will be watching for Orionids that actually hit the Moon.

Cometary debris streams like Halley's are so wide, the whole Earth-Moon system fits inside. So when there is a meteor shower on Earth, there's usually one on the Moon, too. Unlike Earth, however, the Moon has no atmosphere to intercept meteoroids. Pieces of debris fall all the way to the surface and explode where they hit. Flashes of light caused by thermal heating of lunar rocks and moondust are so bright, they can sometimes be seen through backyard-class telescopes.

A map of the morning sky on Saturday, Oct. 22nd at 5:30 a.m. local time, viewed facing southeast. Click to view a larger, more complete map.

"Since we began our monitoring program in 2005, our group has detected more than 250 lunar meteors," says Cooke. "Some explode with energies exceeding hundreds of pounds of TNT."

So far, they've seen 15 Orionids hitting the Moon--"two in 2007, four in 2008, and nine in 2009," recalls Cooke. This year they hope to add to the haul. About 25% of the Moon's dark terrain will be exposed to Halley's debris stream, giving the team millions of square miles to scan for explosions.

Watching meteoroids hit the Moon is a good way to learn about the structure of comet debris streams and the energy of the particles therein. It also allows Cooke and colleagues to calculate risk factors for astronauts who, someday, will walk on the lunar surface again.

"Going outside to watch the Orionids might not be a good idea for a moonwalker," says Cooke.

But it is a good idea for the rest of us. Set your alarm for a few hours before dawn on Saturday morning and enjoy the show.

Announcing First Nationwide EAS Test


Posted by: Damon Penn, Assistant Administrator, National Continuity Programs

As we often say here at FEMA, it's critical that all members of the team, whether its federal, state, local and tribal governments, or the public, have an emergency communications plan. Knowing how you would get in touch with the residents in your communities, or your loved ones, is a key part of how we all can prepare for disasters, both natural and man-made.

One of the most important communications tools that helps federal, state, local, territorial and tribal authorities issue emergency information and warnings to the public is the Emergency Alert System. This system is frequently used and tested at the local level, but to date it has never been tested on the national level. Chances are you have seen or heard the Emergency Alert System tested in your area many times, whether while watching your favorite TV show or listening to the radio.

Today, as part of our larger efforts to strengthen our nation’s preparedness and resiliency, FEMA and the Federal Communications Commission announced that we will conduct the first national-level test of the Emergency Alert System on November 9th of this year at 2 pm eastern. Similar to the way local emergency alert system tests are conducted, the nationwide test will involve television stations (including digital television, cable, satellite audio and television services) and broadcast radio stations across the U.S. and several U.S. territories (Puerto Rico, Virgin Islands, America Samoa) at the same time.

We’re announcing this test date many months in advance because we want all of our partners, and especially the public, to be aware of this test, what it means, and have plenty of time to prepare. To help explain how the test will work and what we can expect, below are some common questions and answers.

What is the Emergency Alert System?

The Emergency Alert System (EAS) is a national alert and warning system established to enable a regional or nationwide alert to address the American public in all 50 states and several territories (additional territories will be capable of receiving EAS messages soon) during emergencies. NOAA National Weather Service, governors and state and local emergency authorities also use it to issue more localized emergency alerts. Under the FCC’s rules, broadcasters, cable operators, Satellite Digital Audio Radio Service providers, Direct Broadcast Satellite service providers and wireline video service providers are required to receive and transmit Presidential EAS messages to the public. While various components of the system are tested regularly, there has never been a nationwide, top-to-bottom, test of the system. Also, to date, the EAS has not been used to deliver a national-level or Presidential alert.

Why is the EAS System being tested now?

The EAS has never been tested on a national level before, and conducting this test is an opportunity to test the system and its capabilities. The EAS test plays a key role in ensuring our nation is prepared for all hazards and people within its borders are able to receive critical and vital information, should it ever be needed.

While EAS tests may be temporarily disruptive to radio and television programming, they are important to ensure that the EAS is functional and that EAS participants are prepared to issue alerts, and it is our intent to minimize disruption and confusion to the extent possible. The November 9 date is near the end of hurricane season and before the severe winter weather season begins in earnest. The 2 PM EST broadcast time will minimize disruption during rush hours, while ensuring that the test occurs during working hours across the United States.

What will people hear and see during the test?

On November 9, the public will hear a message indicating that “This is a test.” The audio message will be the same for both radio and television. However, the image on the screen and the text/crawl at the top of television screen may not be the same for all viewers. When the EAS test is over, regular programming will resume.

As we continue working with all our partners to prepare for the test in the months ahead, FEMA and the FCC plan to conduct outreach to organizations representing people with hearing disabilities to prepare that community for the national EAS test. Outreach will include specific information tailored to the needs of those with hearing disabilities that will be readily available at online sites.

How long will the test last?

We anticipate that the test will last approximately 3 minutes. While most messages, such as tsunami or hurricane warnings, are limited to 2 minutes by the EAS system, the Presidential message capability does not have a time limit. So to evaluate if the system properly interprets the Presidential message code in this test, the message duration must be longer than two minutes in length.

And because, as with all areas of emergency management, this test will involve many members of the team, here is a quick overview of who does what to prepare for a national test:

FEMA develops, operates and maintains the national-level EAS; conduct test and exercises; ensures the national-level EAS keeps pace with emerging technologies through the use of low-cost innovation techniques.

The FCC maintains the regulatory responsibility, rules and enforcement of the Emergency Alert System with broadcasters and wireline service providers.

NOAA’s National Weather Service provides imminent weather threat warnings to the public. During the test, the NWS will provide situational awareness of possible severe weather and climate threats to the United States. If NOAA needs to activate the EAS for severe State/localized weather alerts, test managers may delay the test in that area to make way for the imminent threat weather alert.

State Emergency Operations Centers may monitor the tests and transmissions.

The private sector, including organizations such as the National Association of Broadcasters (including State Broadcast Associations), the Society of Broadcast Engineers (SBE), the National Alliance of State Broadcasters Associations (NASBA), American Cable Association (ACA), the Primary Entry Point Administrative Council (ACA), National Cable and Telecommunications Association (NCTA), Society of Cable Telecommunications Engineers, Broadcast Warning Working Group, and others provide extraordinary input for this test.

This test is another reminder that everyone should establish an emergency preparedness kit and emergency plan for themselves, their families, communities, and businesses. Anyone can visit www.ready.gov for more information about how to prepare for and stay informed about what to do in the event of an actual emergency.

As we continue to work with all our partners in the months leading up to this test, visit the FCC’s Public Safety and Homeland Security Bureau web page, at www.fcc.gov/pshs for updates and developments. We will also continue to post updates on this blog.
