论坛中日全食的照片已经很多了,但重庆当地的很少。我今天来贴一个,这是APOD的,发布时间正如前几天预料的那样。

Eclipse over Chongqing, China

Explanation:
The daytime sky grew dark, the temperature dropped, and lights came on as Chongqing, China, was plunged into the Moon's shadow during the July 22nd total solar eclipse. This serene, wide-angle view of the event looks to the east over the large, populous city from a newly constructed park. Despite thin clouds, it captures the shimmering solar corona just before the end of the eclipse total phase. This total solar eclipse occurred near Aphelion, the point in Earth's elliptical orbit farthest from the Sun, and so the Sun was near its smallest apparent size. It also occurred when the New Moon was near Perigee, the closest point to Earth in the Moon's elliptical orbit, making the Moon near its largest apparent size. The small Sun and large Moon made this the longest solar eclipse of this century.

今天的大图来自北京天文馆镜像,他们今天“翻译”得极快,说不定就是北京天文馆供APOD的图,文字也是先有中文后有英文的。

重庆上空的日全食

说明:
在7月22日日全食期间,重庆慢慢地进入了月球的阴影,白昼慢慢变黑,温度下降,路灯被点亮。这张利用广角镜头拍摄的影像是在一个新建的公园里拍摄。尽管天空中有薄云,但是在全食阶段快结束前还是拍摄到了闪闪发光的日冕。此次日全食发生在远日点附近,也就是在地球椭圆轨道上距离太阳最远的那点上,因此地球上看到太阳的大小处于它最小的相位上。而发生日食时新月正好位于近地点,也就是月球椭圆轨道上距离地球最近的点,这使得看上去月球的相位最大。小太阳加上大月球使得此次日全食成为本世纪时间最长的日全食。

重庆当地显然不是晴空,但薄云条件比江南好多了,那些下雨的地方更不要提了。

OTV直播的海上日全食,可以看见日食带四周天际的霞光,那景象真壮观!这个在本图中没有体现。
