山上的幽灵 A ghost on the mountain

保加利亚中央巴尔干国家公园的布罗肯幽灵

万圣节即将来临，我们呈现了布洛克幽灵的鬼影。尽管出现了，而且这个赛季，布罗肯幽灵并没有什么超自然现象。这是观察者在半空中投射在强光源对面的云上的放大阴影。布罗肯幽灵是罕见的，但在黎明时爬上一座山，爬上雾蒙蒙的山坡，你可能很幸运地看到了这种效果。尽管这种幽灵，也被称为布罗肯弓、山幽灵或布罗肯幽灵，可以出现在条件合适的任何地方，但德国哈兹山脉的山峰布罗肯的浓雾创造了一个当地传说，这一现象由此得名。1780年，约翰·西尔伯施拉格（Johann Silberschlag）观察并描述了布罗肯幽灵，此后，有关该地区的文献中经常有记录。

With Halloween around the corner, we present the ghostly image of a Brocken specter. Despite appearances, and the season, there's nothing paranormal about a Brocken specter. It's the magnified shadow of an observer cast in midair upon a cloud opposite a strong light source. Brocken specters are rare but climb a mountain at dawn up to the misty slopes and you may be fortunate enough to witness the effect. While the specter, also known as a Brocken bow, mountain specter, or specter of the Brocken, can appear anywhere in which conditions are right, the thick fogs of the Brocken, a peak in the Harz Mountains in Germany, have created a local legend from which the phenomenon draws its name. The Brocken specter was observed and described by Johann Silberschlag in 1780 and has since been recorded often in literature about the region.
