GIANT SUNSPOT APPROACHES "THE DANGER ZONE": After a few days of stalled progress, sunspot AR3615 is growing again. A 50% increase in surface area since yesterday has ballooned one of its dark cores to triple the size of Earth. "I saw the sunspot this morning just off the wingtip of an RAF A400," says Marc Charron, who sends this picture from Ayr, Scotland:
"The plane was doing training circuits from Prestwick, Scotland, and on one pass it crossed the sun from where I was standing," says Charron. "The massive sunspot group AR3615 was clearly visible through the clouds, while AR3619 and AR3614, respectively, can be seen above that group."
As Charron's photo shows, AR3615 is approaching the western edge of the sun. That's "the danger zone." Sunspots located there are magnetically connected to Earth via the Parker Spiral. If AR3615 erupts while it is transiting the danger zone, energetic protons and electrons may be funneled back toward our planet for a days-long radiation storm. Stay tuned!
巨大的太阳黑子接近“危险地带”:经过几天的停滞不前，太阳黑子AR3615又开始生长了。自昨天以来，它的表面积增加了50%，其中一个暗核的体积膨胀到了地球的三倍。“今天早上，我在一架英国皇家空军A400的翼尖上看到了太阳黑子，”马克·查伦说，他从苏格兰艾尔发来了这张照片:
“这架飞机当时正在从苏格兰的普雷斯特威克进行训练，有一次它从我站的地方飞过太阳，”Charron说。“通过云层可以清楚地看到巨大的太阳黑子群AR3615，而AR3619和AR3614分别可以在该团的上方看到。”
正如Charron的照片所示，AR3615正在接近太阳的西部边缘。那就是“危险地带”。位于那里的太阳黑子通过帕克螺旋与地球磁连接。如果AR3615在穿越危险区域时爆发，高能质子和电子可能会聚集回我们的星球，形成长达数天的辐射风暴。请继续关注!
