Geomagnetic Storm Subsiding:

Just before 12:00 UTC Monday, the ACE Spacecraft detected a solar wind increase from 350 km/s to over 700 km/s at its peak. This indicated the arrival of a the Coronal Mass Ejection (CME) sweeping past the spacecraft which was the result of a long duration M7.1 Solar Flare on Sept. 24. The Bz had titled sharply south at times (-30nT) and a Strong G3 to G4 Level Geomagnetic Storm occurred at high latitudes. Less severe Geomagnetic Storming took place at middle latitudes. Because the timing of the CME shock was early in the day, visible Aurora would have favored Europe and not here in North America.

Many Aurora contacts were made on the 2m (144mhz) and 6m (50mhz) amateur radio bands in both Northern Europe and Northern parts of Canada and USA.

GEOMAGNETIC STORM--IN PROGRESS: High-latitude sky watchers should be alert for auroras. A strong (Kp=7) geomagnetic storm is in progress. Aurora alerts: text, voice.​

Earth's magnetic field has been strongly disturbed since approximately 1300 UT on Sept. 26th when a CME hit our planet. The impact strongly compressed the magnetosphere, exposing geosynchronous satellites to solar wind plasma, and ignited auroras around both poles. Gordon McLellan photographed these pastels over Lake Michigan after sunset on Sept. 26th:

 

On September 27, 2011 there were 1250 potentially hazardous asteroids. ​

ลูกไฟตกจากฟ้า เผาบ้านไปสองหลังที่อาเจนติน่า และเกิดขึั้นในซีแอตเทิล

Alejandro Sack
Something unusual apparently occured here in my country Argentina. Two houses blew up due to what the neighbours of that urban area describe as a red ball of fire coming down from the sky. This happened today at 2.15 am local time (GMT Buenos Aires: -3.00). The "shock wave" of the explosion extended to a couple of blocks from impact zone. Some neighbours said that before they heard the explosion a blightning light turn the night into day. A strong hyphothesis is a meteor impact, although the remains of the houses are just now being gathered and no crater has been found yet. The authorities say that there's a specific igneous spot, and no fire has been put out cos there was none. I´m posting an image of, apparently, the object that hit the houses. Sorry for my english

Mystery explosion and Esteban Echeverría, "a ball of fire fell from heaven"

One woman died and six others were injured in the incident. A neighbor said the outbreak was caused by a burning object that fell from the sky and completely destroyed a house and several cars. "It was a tremor," he said. Are the causes of the accident.

The incident occurred minutes before 2 am, in a building located on the intersection of Luis Vernet and Los Andes, a town of Monte Grande, of Esteban Echeverría. The causes of the explosion are still unknown, but locals say they witnessed the fact that "a ball of fire fell from heaven." "He began to feel much smell like gunpowder," recalled one person who lives in the area told C5N. "There is no explanation for what happened," said Cayetano, a local resident, told Radio 10, then adding, "a neighbor ran because he saw a fireball falling blue." The commander of the local fire department, Guillermo Pérez, remarked that still do not know the cause of the incident, but acknowledged that the first version is aimed at an "object that fell from heaven." "I heard that version, but I can not say at first. Must be bound to expertise to really see what happened, "he said in a statement to Radio 10. Perez confirmed that two trade houses and" were completely destroyed. "In fact, a woman who was trapped under the rubble lost life while six others were rescued and were taken for care at a local hospital, told C5N firefighters who work on site.

The victim is one of the people who lived in the building where the explosion was generated. As the injured, three belong to that house and three adjoining the house, hit by the blast. All the injured were out of danger, said C5N. According to the story of neighbors, the outbreak was felt even in adjoining towns like Ezeiza and Temperley, south of Buenos Aires

WASHINGTON -- NASA will hold a news conference at 1 p.m. EDT (10 a.m. PDT) on Thurs., Sept. 29, to reveal near-Earth asteroid findings and implications for future research. The briefing will take place at NASA Headquarters in Washington.

NASA's Wide-field Infrared Survey Explorer (WISE) mission, launched in December 2009, captured millions of images of galaxies and objects in space. During the news conference, panelists will discuss results from an enhancement of WISE called Near-Earth Object WISE (NEOWISE) that hunted for asteroids.

The panelists are:
--Lindley Johnson, Near-Earth Object program executive, NASA Headquarters, Washington
--Amy Mainzer, NEOWISE principal investigator, NASA's Jet Propulsion Laboratory, Pasadena, Calif.
--Tim Spahr, director, Minor Planet Center, Smithsonian Astrophysical Observatory, Cambridge, Mass.
--Lucy McFadden, scientist, NASA's Goddard Space Flight Center, Greenbelt, Md.

The event will air live on NASA Television and the agency's website. For NASA TV streaming video, downlink and scheduling information, visit: http://www.nasa.gov/ntv . It will also will be streamed live, with a moderated chat available, at: http://www.ustream.tv/nasajpl2 .

"Dark" Supermoon September 27th: New Moon Gets Closest to Earth

A crescent moon is barely visible as the sun sets over Montana in a 2008 picture.

Tomorrow night the new moon will make a close approach to Earth, giving rise to the second supermoon of the year - but this one will have the power of invisibility.

Because the moon's orbit is egg shaped, there are times in the roughly monthlong lunar cycle when the moon is at perigee - its closest distance to Earth - or at apogee, its farthest distance from Earth.

"A supermoon occurs when the moon is at perigee and it's in either a full or new phase," said Raminder Singh Samra, an astronomer at the H.R. MacMillan Space Centre in Vancouver, Canada.

In March sky-watchers were treated to a full moon at perigee, which made for the biggest full moon seen in 18 years.

(See "Supermoon Pictures: Best Shots of Biggest Full Moon.")

A new moon happens when the lunar orb positions itself between Earth and the sun, so that the side of the moon that faces Earth is unlighted.

"The upcoming moon on September 27, 2011, is set to be at perigee and at the new phase," Samra said, "so we won't be able to witness the event, as the moon and sun will be in the same region of the sky" and the lunar disk will be entirely dark.

Supermoon to Affect Earth's Tides?

Because the size of the moon's orbit also varies slightly, each perigee is not always the same distance from Earth.

When at perigee, the moon is about 18,640 miles (30,000 kilometers) closer to Earth than its average distance of roughly 240,000 miles (385,000 kilometers). When perigee occurs during a full moon, the lunar disk can appear about 14 percent bigger in the sky, Samra said.

Tuesday's dark supermoon will be just 222,175 miles (357,557 kilometers) away from Earth.

Some people have speculated that this lunar proximity can have unusual gravitational effects on Earth, triggering dramatic events such as earthquakes.

(Take a moon myths and mysteries quiz.)

But the truth is that there's only a very small correlation between full or new moons and seismic stresses, said Jim Todd, planetarium manager at the Oregon Museum of Science and Industry.

"Stronger tidal forces caused by the alignment of the sun and moon may put added stress on tectonic plates," Todd said.

"However, seismologists have found no evidence connecting lunar perigees to heightened seismic activity. Instead the Earth constantly stores up energy and releases it any time the built-up energy becomes too great."

Lunar close encounters are well known to cause slightly higher ocean tides, so any localized flooding during a supermoon would be most noticeable around beaches and other low-lying areas.

(Related: "Hurricane Irene 'Looking Bad' for U.S. - Moon May Make It Worse.")

But linking the supermoon to effects beyond that is far-fetched, the H.R. MacMillan Space Centre's Samra said.

"While the supermoon is thought to provoke various natural disasters on the Earth," he said, "such claims are exaggerations, as there is simply no scientific evidence for them."

 

Laser-powered communication offers high res photos for NASA

Impatient boffins will be able to download high resolution images and video from space probes in mere minutes if a newly approved NASA trial proves successful.

The has rubber-stamped a trial of one of its projects - a laser-based communications system - which is theoretically capable of shifting up to 100Mb/s from spacecraft poking around the furthest corners of the solar system.

NASA’s current space communications and data transfers are done on radio frequency (RF) systems. The RF systems’ data transmission rates mean that it takes 90 minutes for a single high-resolution image to be beamed back to from Mars. The new laser-based system would allow 100Mbps data rates instead of 6Mbps, allowing a image to be transmitted in five minutes.

“Just as the home internet user hit the wall with dial-up, NASA is approaching the limit of what its existing communications network can handle,” said Dave Israel, who will lead the project.

BIG SUNSPOT: The source of the CME that hit Earth on Sept. 26th is sunspot AR1302. Measuring more than 150,000 km from end to end, the sprawling active region is visible even without a solar telescope. Here it is among the seagulls at sunset on Sept. 27th:


​

​

Damien Vens took the picture from the beach in Koksijde, Belgium. "I used an off-the-shelf Nikon D7000 digital camera," he says. "The sunspot was an easy target." (Note to photographers: Never look at the sun through unfiltered optics such as camera viewfinders; even a low-hanging sun can be blindingly bright.)

​

AR1302 has quieted down since unleashing dual X-flares on Sept. 22nd and 24th. Nevertheless, NOAA forecasters estimate a 25% chance of more X-flares during the next 24 hours. Any such eruptions would be Earth-directed as the sunspot crosses the center of the solar disk. Solar flare alerts: text, voice.

จุดดับใหญ่: ตัวก่อกำเนิด CME ที่มาปะทะโลกในวันที่ 26 กันยายน คือ จุดดับ AR1302. วัดแล้วจากหัวถึงปลายได้ความยาวกว่า 150,000 กิโลเมตร และก็แผ่ไปทั่วพื้นที่ และมองเห็นได้แม้ไม่ต้องใช้กล้องดูดาว ในรูปคือนกนางนวล ขณะที่พระอาทิตย์ตกวันที่ 27 กันยายน



จุดดับ AR1302 ได้เงียบลงสักพักตั้งแต่พ่น flare X-Flare มาสองลูกติดกัน ในวันที่ 22 และ 24 กันยายน ถึงอย่างไรก็ตาม NOAA ได้คาดว่ามีโอกาสถึง 25% ที่จุดดับนี้จะพ่น X-flare ออกมาระหว่าง 24 ชั่วโมงข้างหน้า การระเบิดลูกใดๆ ตอนนี้ คือ จะตรงมายังโลกตรงๆ (เพราะตอนนี้จุดดับตรงกับโลกพอดี ผู้แปล) จุดดับนี้ตั้งอยู่ใจกลางของดวงอาทิตย์พอดี
