Sunspot 875 Flares

Explanation: An unusually active sunspot region is now crossing the Sun. The region, numbered 875, is larger than the Earth and has produced several solar flares over the past week. It should take a few more days for Sunspot 875 to finish crossing the solar disk. The above image of the Sun was taken last Wednesday in a very specific color of red light to bring up detail. Sunspot 875, in the midst of erupting a large Class C solar flare, can be seen as the dark region to the upper right. In the above image, relatively cool regions appear dark while hot regions appear bright. On the far left, solar prominences are visible hovering above the Sun's surface.
解释: 一不寻常的黑子活动区域正在穿越太阳.编号为875的区域比地球还要大, 在上周,还制造了数个太阳耀斑.太阳黑子875还将花费数周的时间才能完全穿越太阳的盘面 .上面这张拍摄于上周三的图像中,为了突出细节,而采用了一很特殊的红光拍摄.太阳黑子875,在一个巨大的喷发中的C类太阳耀斑之中,可以看到右上的黑暗区域.上图中,温度较低的地区表现为黑色,而炽热的地区则显得很明亮. 左方远处,可以看到日珥在太阳表面徘徊.
