质子流猛升中，根据STEREO-A的数据，估计还有几十分钟到L1了
准备开启追击计划

3664起飞了，过去半天总体X射线流量一直维持在M水平
喷了个X1.0 long duration，可以看到halo，具体啥情况 ...

这是两个黑子群合并而来的，磁极性属于最为稀有的gamma-delta类型，完全看不出普通黑子群整体前导-后随的两极性，就是一锅乱饨。

好家伙，这已经不只是干爆表了

佛罗里达都出现了极光
AURORAS IN FLORIDA! Many people around the world have just seen auroras for the first time in their lives. This includes residents of the Florida Keys. Ron Jarrell sends this photo from Big Pine Key at latitude 24.7° N:"The auroras were so beautiful!" says Jarrell, who may have made the lowest latitude sighting during this storm. (Update: We now have a credible report of auroras in Puerto Rico!)

Other low latitude sightings of note include St John’s, Florida (30.1° N); Ocala, Florida (29.2° N); Shallowater, Texas (33.7° N); Sedona, Arizona (34.9° N); Cave Creek, Arizona (33.8° N); San Antonio, Texas (29.4° N); Augusta, Georgia (33.5° N); Montezuma, Georgia (32.3° N); and Auburn, Alabama (32.6° N). Stay tuned for more! Aurora alerts: SMS Text
佛罗里达的极光!世界上很多人都是有生以来第一次看到极光。这包括佛罗里达群岛的居民。罗恩·贾雷尔从北纬24.7°的大松岛发来了这张照片:“极光太美了!”贾雷尔说，他可能是在这场风暴中看到最低纬度的人。(更新:我们现在有了关于波多黎各极光的可靠报道!)

其他值得注意的低纬度目击事件包括佛罗里达州的圣约翰(北纬30.1度);佛罗里达州奥卡拉(29.2°N);浅水，德克萨斯州(33.7°N);亚利桑那州塞多纳(34.9°N);亚利桑那州的Cave Creek(33.8°N);德克萨斯州圣安东尼奥(29.4°N);乔治亚州奥古斯塔(北纬33.5度);格鲁吉亚蒙特祖玛(北纬32.3度);阿拉巴马州奥本(北纬32.6度)。敬请期待!极光警报:短信文本

THE STRONGEST X-FLARE YET: Giant sunspot AR3664 unleashed another X-flare today (May 11th @ 0139 UT)--its strongest yet. NASA's Solar Dynamics Observatory captured a bright ultravolet flash from the category X5.8 explosion:

Radiation from the flare caused a deep shortwave radio blackout over the Pacific Ocean. Ham radio operators and mariners may have noticed loss of signal at frequencies below 30 MHz for as much as an hour after the flare's peak.

We don't yet know if this flare hurled a CME into space. If it did, it could have a grazing Earth-directed component. Confirmation awaits fresh data from SOHO coronagraphs.
迄今为止最强的x -耀斑:巨大的太阳黑子AR3664今天(5月11日0139 UT)释放了另一个x -耀斑，这是迄今为止最强的。美国宇航局的太阳动力学观测站从X5.8级爆炸中捕捉到明亮的紫外线闪光:

耀斑的辐射导致太平洋上空短波无线电中断。业余无线电操作员和水手可能已经注意到在30兆赫以下频率的信号丢失，在耀斑达到峰值后长达一个小时。

我们还不知道这次耀斑是否向太空中投掷了CME。如果是的话，它可能有一个放牧地球的成分。确认等待SOHO日冕仪的新数据。
