เหตุการณ์ใน-นอกโลก VS ภัยธรรมชาติ และupdate พายุสุริยะ

AURORA WHIRLPOOL: On Feb. 14-15, Arctic skies erupted with an unexpected display of auroras that veteran observers said was among the best in months. At the height of the event, a US Defense Meteorological Program satellite photographed a whirlpool of Northern Lights over the Bering Sea:​

​

"A number of images from the DMSP F18 satellite captured the dramatic auroral event of the last couple nights," says analyst Paul McCrone, who processed the data at the US Navy's Fleet Numerical Meteorology and Oceanography Center in Monterey, CA.​

The reason for the outburst is still not completely clear. It started on Feb. 14th when a magnetic disturbance rippled around the north pole. No CME was obvious in local solar wind data at the time; the disturbance just happened. Once begun, the display was amplified by the actions of the interplanetary magnetic field (IMF). The IMF near Earth tipped south, opening a crack in our planet's magnetic defenses. Solar wind poured in and fueled the auroras.

Solar Update / New Sunspot 1422
Solar activity increased with C-Class flare activity being detected, including a C4.1 s/f around Sunspot 1421 in the northeast quadrant. New Sunspot 1422 which is also located in the northern hemisphere, continues to expand, and there is now a small chance for an M-Class event.

CRESCENT MOON ALERT: Look low and west at sunset. An exquisitely, almost invisibly slender crescent Moon is beaming through the twilight. Jens Hackmann sends this lucky shot from Weikersheim, Germany:​

​

"It was a lucky shot," explains Hackmann, "because many planes were criss-crossing the sky, but not one of them got in the way of the Moon." ​

Seeing such a slender Moon is difficult, but it will become easier in the nights ahead as the waxing crescent ascends the evening sky for a dazzling close encounter with Venus and Jupiter. The best nights to look: Feb. 25th and 26th. Get the full story and a [ame="http://www.youtube.com/watch?v=x8br4JiFEik"]video[/ame] from Science@NASA.

Situation Update No. 1
On 2012-02-23 at 04:21:05 [UTC]

Event: Event into space
Location: Canada Province of Saskatchewan North Battleford area

Situation:For about four seconds Tuesday night the Lloydminster sky was lit up by a fireball. Shortly after 8:40 p.m. local time on Feb. 21 the fireball streaked across the sky. Witness accounts said the light was mostly contained to the southeast corner of the sky. According to Dr. Alan Hildebrand, University of Calgary associate professor and coordinator of the Canadian Fireball Reporting Centre, said the fireball was likely a meteorite. “We know quite a bit actually already,” said Hildebrand. “The fireball was recorded by one all-sky camera by Lucky Lake and one near Calgary. With the two of those we have a good start in terms of understanding, directions and time.” Hildebrand collected information from eyewitness accounts and shared it with the Meteorites and Impacts Advisory Committee. He said the fireball’s end point was near Rockhaven, Sask., which is southwest of North Battleford, Sask. Witness accounts indicate an apparent magnitude of flares brighter than -15, compared to the sun which has a magnitude of -26.7 and the moon’s is -12.6 in terms of brightness. “The end of it was somewhere around Rockhaven and it was coming from the northeast,” said Hildebrand. The fireball traveled towards 240 degrees with a moderate down angle. The brightness was supplemented by delayed sounds, typically a boom, from witnesses in both Rockhaven and North Battleford. According the Hildebrand the fireball had a strong flare for about one second, which is typical of a reasonably strong rock and fireball duration, suggesting an impact velocity of about 20 kilometres per second. The brightness of the fireball suggests it had an initial mass greater than 100 kilograms. Based off the brightness and the sound Hildebrand said meteorites probably fell. “I don’t know where yet, exactly,” said Hildebrand. Though this is the second major fireball in the Lloydminster sky over the past four years, Hildebrand said several bright fireballs could be visible to the night sky in a given year. “In terms of how often meteorites fall, with rocks on the ground. Say a rock the size of your first on the ground in Canada, each year, would have 70 to 100 different cases of a meteorites falling,” said Hildebrand. In November 2008, the Buzzard Coulee meteorite lit up the Lloydminster sky. The fireball and subsequent meteorite impact left small shards of the meteor, believed to have been about 10 tonnes, scattered throughout the area. At the time Hildebrand came out and further researched the impact and meteorite finds.
