Explanation:
On June 2nd, clouds over Stuttgart, Germany parted to reveal what has become a relatively rare sight, spots on the Sun. In fact, the roughly 11-year solar activity cycle is still in a surprisingly deep minimum and the years 2008 and 2009 have had the lowest sunspot counts since the 1950s. Even the latest prediction is that the new cycle, Solar Cycle 24, will reach a maximum in May 2013 with a below-average sunspot count. The Solar Cycle 24 sunspots recorded here are in active region AR 1019. Previously, only two cycle 24 active regions with sunspots, AR 1018 and AR 1017, were seen in May. 论坛网速太慢了,这2天我将尽量少发图

烏雲與太陽黑子

說明:
6月2日,烏雲籠罩在德國Stuttgart的上空,讓最近很罕見的太陽黑子得以現蹤。依太陽大約11年的活躍週期來看,我們現在還在意外地深的極小期之中,2008年和2009年的太陽黑子數量,是1950年代以來最少的。依照最新的預測,第24太陽週期將在2013年的5月達到極大期,而其黑子數量將比平均值要低。上面這個屬於太陽第24週期的黑子群,其編號為AR 1019。在此之前,頭兩個第24週期的黑子群出現在今年的5月。 IE8发帖怎么这么不方便,microsoft要好好努力了,不要它的产品都成了White elephant,印度阿三写的软件都是又大又笨,可用性也不好。 Stuttgart,这个不翻译没道理,大家知道斯图加特吧,就是它了! 终于出现了::070821_13.jpg::
