ทำไมจุดดับเยอะจัง?

 

[FONT=Arial, Helvetica, sans-serif]CME IMPACT: [/FONT]As predicted by analysts at the Goddard Space Weather Lab, a coronal mass ejection (CME) hit Earth's magnetic field at ~03:30 UT on Sept 17th. The impact was not strong. Nevertheless, the arrival of the CME could spark geomagnetic activity around the Arctic Circle. High-latitude sky watchers should be alert for auroras.

ผลกระทบของ CME: ที่คาดว่า CME จะมาถึงโลกประมาณ 3.30 UTC 10.30 น. โดยประมาณของวันที่ 17 กันยา แต่ผลกระทบไม่ได้รุนแรงเลย แต่อย่างไรก็ตามการมาของ CME ก็ทำให้สนามแม่เหล็กโลกแปรปรวน คอยดูท้องฟ้าแถวขั้วโลกได้เลย

[FONT=Arial, Helvetica, sans-serif]REENTRY ALERT: [/FONT]NASA reports that UARS, an atmospheric research satllite the size of a small bus, will re-enter Earth's atmosphere on Sept. 23, plus or minus one day. Not all of the spectacularly-disintegrating spacecraft will burn up in the atmosphere; debris could be scattered along a ground track some 500 miles long. Because of the rapid evolution of UARS's decaying orbit, the location of the debris zone is not yet known. A NASA risk assessment places the odds of a human casualty at 1:3200. For last-chance sightings of UARS, check the Simple Satellite Tracker or download the Satellite Flybys app for your smartphone.

จะมีดาวเทียมประมาณขนาดของรถบัสคันเล็ก ตกมายังโลกวันที่ 23 กันยา +-1 วัน แต่ว่าคนเผาไหม้ ไปในอากาศ เศษมันจะตกแถวๆ ไหนก็ไม่รู้

 

พระอาทิตย์ตกแบบบ้ามาก

[FONT=Arial, Helvetica, sans-serif]WILD AND CRAZY SUNSET: [/FONT]"Last night I decided to hunt for a green flash," says photographer Mila Zinkova of San Francisco. "So I took my camera to the beach to watch the sunset." She found what she was looking for--and much more. Scan the snapshots in full size, then read the description below:​

​

"I was watching the the mock-miraged sun slowly descend toward the horizon when suddenly it was eclipsed," says Zinkova. "A big ship was passing just in front of the sun. A distorted fragment of sun rose above the ship like a solar prominence and just below it there was a green flash! After the ship passed I observed a few more green flashes. I also captured sunspots in some frames--not to be mistaken with birds."

​

The California Coast is a good place to see these things. The combination of cold offshore ocean current and warm winds from the land create temperature inversions that bend the sun’s rays to form fantastic mirages and green flashes. Birds, ships, and sunspots add their own distinctive contribution to the wild-and-craziness. More of Zinkova's California sunset-shots may be found here.​

 

คาดเหตุการณ์จะเกิดระหว่างช่วงสองสามวันนี้

วันที่ 20 กันยายน จะมีการเรียงตัวของดวงอาทิตย์ โลก และ ดวงจันทร์ ในแนวตั้งฉาก นอกจากนั้นยังมีการเรียงตัวระหว่าง ดวงอาทิตย์ ดาววีนัส และ ดาวเสาร์ เวลา 3 UTC คาดว่าโลกจะเสี่ยงต่อแผ่นดินไหวเกิน 6.4 ริตเตอร์ ระหว่าง 19-24 กันยายน ด้วยความน่าจะเป็น 90%








วันที่ 16 กันยายน จุดดับเพิ่มจำนวนสูงสุด เป็นลางบอกเหตุว่าจะเกิดแผ่นดินไหวระดับเกิน 6.4 ริตเตอร์ ระหว่างวันที่ 17-21 กันยายน


วันที่ 17 กันยายน เวลา 2:24 UTC เกิดพายุสุริยะขนาดปานกลาง-มาก ทิศทางมาในแนวเดียวกับโลก คาดว่าจะส่งผลกระทบต่อโลกในวันที่ 19-20 กันยายน นอกจากนั้นปริมาณจุดดับขึ้นสูงสุดถึง #173 ซึ่งมีแนวโน้มจะเกิดแผ่นดินไหวขนาดใหญ่ภายใน 1-3 วัน


จับตาการเรียงตัวของดาวเคราะห์ช่วงวันที่ 15 กันยายน - 4 ตุลาคม คศ 2010 : update 19 กันยายน เวลา 0:26 UTC | Truth4Thai.org

[FONT=Arial, Helvetica, sans-serif]FOUR CMEs: [/FONT]On Sept. 19th, the STEREO-SOHO fleet of spacecraft surrounding the sun detected six coronal mass ejections (CMEs). Two of the clouds rapidly dissipated. The remaining four, however, are still intact and billowing through the inner solar system. Click to view a movie of their forecasted paths:


​

​

According to analysts at the Goddard Space Weather Lab, who prepared the movie, one CME should hit Mercury on Sept. 20th at 05:40 UT while another delivers a glancing blow to Earth's magnetic field on Sept. 22th at 23:00 UT. All impact times have an uncertainty of plus or minus 7 hrs.

[FONT=Arial, Helvetica, sans-serif]UARS, CONTINUED: [/FONT]NASA's UARS satellite is making its final orbits around Earth, tumbling and flashing brightly as it descends toward a Sept. 23rd re-entry. Amateur astronomer Jim Saueressig II caught the bus-sized satellite flying over Burlington, Kansas, on Sept. 20th (image). "It was easily visible in spite of the moonlight and the twilight of the sunrise. The tumble and associated flares were very apparent," he says.


​

Satellite tracking expert Ted Molczan has used USSTRATCOM's orbital elements of UARS to predict a decay time "late on Sep 23, roughly between 18:00 and 22:00 UTC." Click on the map to view ground tracks corresponding to this interval:

​

​

"There is still potential for the estimated time of decay to shift somewhat before it begins to narrow down," cautions Molczan.

​

The disintegration of UARS is expected to produce a fireball that could be visible even in broad daylight. Not all of the spacecraft will burn up in the atmosphere, however; according to a NASA risk assessment, as many as 26 potentially hazardous pieces of debris could be scattered along a ground track some 500 miles long. The same report puts the odds of a human casualty at 1 in 3200.

[FONT=Arial, Helvetica, sans-serif]RE-ENTRY UPDATE: [/FONT] NASA has issued an update on the condition of the decaying UARS satellite: "As of 1:30 p.m. EDT Sept. 21, 2011, the orbit of UARS was 120 mi by 130 mi (190 km by 205 km). Re-entry is expected sometime during the afternoon of Sept. 23, Eastern Daylight Time.

The satellite will not be passing over North America during that time period. It is still too early to predict the time and location of re-entry with any more certainty, but predictions will become more refined in the next 24 to 48 hours."

Track NASA's Falling, 6.5-Ton Satellite in Real-Time


Published September 21, 2011
| FoxNews.com


NASA
An artist's concept of the Upper Atmosphere Research Satellite (UARS) satellite in space. The 6 1/2-ton satellite was deployed from space shuttle Discovery in 1991 and decommissioned in December 2005.



In a matter of days, the sky will actually be falling.
A defunct NASA atmosphere-monitoring satellite the size of a small bus is set to plunge to Earth somewhere between Thursday and Saturday -- and the space agency's scientists say there's no way to precisely determine where it will crash, be it Africa or America, the Pacific Ocean or Pacific Heights.


But thanks to a neat widget built exclusively for FoxNews.com by the satellite-tracking website N2YO.com, you can watch the UARS satellite as it courses through the heavens -- see the embedded module below.

FEMA Prepared In Case Plunging Satellite Hits U.S.
Emergency agency readies for 6.5-ton piece of space debris to hit Earth


Pinpointing where and when hurtling space debris will strike is an imprecise science. To calculate the orbit, N2YO.com runs information from the U.S. Air Force Space Command through a series of algorithms, and overlays it on mapping data from Google.
For now, scientists predict the earliest it will hit is Thursday U.S. time, the latest Saturday. The strike zone covers most of Earth.
Not that citizens need to take cover. The satellite will break into pieces, and NASA put the chances that somebody somewhere will get hurt at just 1-in-3,200 -- low enough that some people are making a game of the whole thing.
One Irish company is even allowing people to gamble on the crash site. Paddy Power, Ireland's largest bookmaker, has placed the odds that the satellite will crash in the Pacific Ocean at 8/11, followed by the Atlantic at 2/1.
“This is an absolute lottery," a spokesman for the site said. "It really could land anywhere, but I think it would be best for everyone if the satellite went for a dip.”
As far as anyone knows, falling space debris has never injured anyone. Nor has significant property damage been reported. That's because most of the planet is covered in water and there are vast regions of empty land.
If you do come across what you suspect is a satellite piece, NASA doesn't want you to pick it up. The space agency says there are no toxic chemicals present, but there could be sharp edges. Also, it's government property. It's against the law to keep it as a souvenir or sell it on eBay. NASA's advice is to report it to the police.
The 20-year-old research satellite is expected to break into more than 100 pieces as it enters the atmosphere, most of it burning up. Twenty-six of the heaviest metal parts are expected to reach Earth, the biggest chunk weighing about 300 pounds (136 kilograms). The debris could be scattered over an area about 500 miles (800 kilometers) long.

Due to heavy demand, the module below -- built exclusively for FoxNews.com by N2YO.com -- may take several minutes to load. ​

Jonathan McDowell, for one, isn't worried. He is in the potential strike zone -- along with most of the world's 7 billion citizens. McDowell is with the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts.


"There's stuff that's heavy that falls out of the sky almost every year," McDowell says. So far this year, he noted, two massive Russian rocket stages have taken the plunge.
As for the odds of the satellite hitting someone, "it's a small chance. We take much bigger chances all the time in our lives," McDowell says. "So I'm not putting my tin helmet on or hiding under a rock."
All told, 1,200 pounds (544 kilograms) of wreckage is expected to smack down -- the heaviest pieces made of titanium, stainless steel or beryllium. That represents just one-tenth the mass of the satellite, which stretches 35 feet (10.7 meters) long and 15 feet (4.6 meters) in diameter.
The strike zone straddles all points between latitudes 57 degrees north and 57 degrees south. That's as far north as Edmonton and Alberta, Canada, and Aberdeen, Scotland, and as far south as Cape Horn, the southernmost tip of South America. Every continent but Antarctica is in the crosshairs.
Back when UARS, the Upper Atmosphere Research Satellite, was launched to study the ozone layer in 1991, NASA didn't always pay attention to the "what goes up must come down" rule. Nowadays, satellites must be designed either to burn up on re-entering the atmosphere or to have enough fuel to be steered into a watery grave or up into a higher, long-term orbit.
The $740 million UARS was decommissioned in 2005, after NASA lowered its orbit with the little remaining fuel on board. NASA didn't want to keep it up longer than necessary, for fear of a collision or an exploding fuel tank, either of which would have left a lot of space litter.
If it happens in darkness, it should be visible.
"If someone is lucky enough to be near the re-entry at nighttime, they'll get quite a show," says Matney, who works at Johnson Space Center in Houston, also in the potential strike zone.
