9月10日晚出现木闪奇观
EXPLOSION ON JUPITER: Apparently, something hit Jupiter during the early hours of Sept. 10th (11:35 UT), igniting a ferocious fireball in the giant planet's cloudtops. Amateur astronomer Dan Peterson Racine, Wisconsin, saw it first through his Meade 12" LX200 telescope. "It was a bright white flash that lasted only 1.5 - 2 seconds," he reports. Another amateur astronomer, George Hall of Dallas, Texas, was video-recording Jupiter at the time, and he confirmed the fireball with this video screenshot:http://spaceweather.com/images2012/11sep12/jupiterimpact_strip3.jpgImpact site coordinates: longitude 335o (system 1) and latitude +12o, inside the North Equatorial Belt's southern section. The fireball was probably caused by a small asteroid or comet hitting Jupiter. Similar impacts were observed in June and August 2010. An analysis of those earlier events suggests that Jupiter is frequently struck by 10 meter-class asteroids--one of the hazards of orbiting near the asteroid belt and having such a strong gravitational pull.
Astronomers around the world will now begin monitoring the impact site for signs of debris--either the cindery remains of the impactor or material dredged up from beneath Jupiter's cloud tops. Some impacts do produce such debris, while others don't. Researchers aren't sure why; perhaps this event will provide some clues. Stay tuned for news about what happens next.谷歌翻译 大意：爆炸在木星：显然，东西撞木星在9月10日（11:35 UT）凌晨，在巨行星的cloudtop，引发了凶猛的火球。另一位业余天文学家乔治·霍尔的达拉斯，得克萨斯州，是业余天文学家丹·彼得森拉辛，威斯康星州，通过他的米德12“LX200望远镜第一次看见它。”这是一个明亮的白色闪光，持续时间只有1.5 -2秒，“他的报告。视频记录木星的时候，他证实了此视频截图火球：
撞击点坐标：东经335o（系统1）和纬度+12ö，北赤道带的南段内。
可能是由一个小的小行星或彗星击中木星的火球。类似的影响，观察在6月和2010年8月。这些早期事件的分析表明，木星经常10米级小行星撞击 - 轨道附近的小行星带，有这样一个强大的引力的危害之一。
现在，世界各地的天文学家开始监视的迹象碎片撞击点 - 无论是灰烬仍然是木星的云层的下方疏浚的冲击或材料。有些影响，产生这些碎片，而另一些则没有。研究人员不知道为什么，也许是本次活动将提供一些线索。敬请期待接下来会发生什么新闻。 本帖最后由 q零度星系 于 2012-9-11 14:51 编辑
http://georgeastro.weebly.com/uploads/1/3/3/4/13344093/jupiterimpact.jpgAn apparent object impact captured about 6:35 am on Sept. 10, 2012 from Dallas, Texas USA. The impact was observed by Dan Peterson visually this morning. His observation was posted later on the ALPO_Jupiter forum. When I saw the post, I went back and examined the videos that I had collected this morning. Click on the image to the leftto see a larger version. This is a screen capture from QuickTime of a single frame from the video. The video was captured with a 12" LX200GPS, 3x Televue Barlow, and Point Grey Flea 3 camera. The capture software was Astro IIDC.谷歌翻译大意：一个明显的目标影响约6:35拍摄于2012年9月10日上午从美国德克萨斯州的达拉斯，。今天上午由丹·彼得森视觉上的影响。他的观察之后的ALPO_Jupiter论坛。当我看到后，我就回去和审查的影片，我已经收集了今天上午。点击图片的左侧看到一个更大的版本。这是一个屏幕捕获从一个单一的帧从视频的QuickTime。 12“LX200GPS，3 Televue巴洛，点灰色跳蚤3相机拍摄的视频捕获软件是天文IIDC。http://georgeastro.weebly.com/uploads/1/3/3/4/13344093/20120909_055204_lrgb_crop.jpgScope: LX200GPS 12" F30, Optical Attachments: 3x TeleVue Barlow, Camera: Point Grey Flea 3 Firewire, Mount: LX200, Super Field Tripod, Super Wedge.

太阳系内天体之间的碰撞应该并不少见，但被人类观测到的不多。1994年7月苏梅克-利维彗星撞击木星事件是迄今为止人类直接观测到的唯一一类这类碰撞事件。前几年小行星Scheila突然出现扇状尾巴，据估计也是由碰撞事件产生。

值得收藏。 肉眼看到肯定壮观，但多少要点想象力…
