Explanation: Want to watch a solar eclipse safely? Try looking down instead of up, though you might discover you have a plethora of images to choose from. For example, during the June 21st solar eclipse this confusing display appeared under a shady bamboo grove in Pune, India. Small gaps between close knit leaves on the tall plants effectively created a network of randomly placed pinholes. Each one projected a separate image of the eclipsed Sun. The snapshot was taken close to the time of maximum eclipse in Pune when the Moon covered about 60 percent of the Sun’s diameter. But an annular eclipse, the Moon in silhouette completely surrounded by a bright solar disk at maximum, could be seen along a narrow path where the Moon’s dark shadow crossed central Africa, south Asia, and China.

说明:想用安全的方式看日食吗?试着往下看,不过,或许你会发现可供选择的标的太多。这片令人眼花撩乱,6月21日日食期间,摄于印度浦纳一片竹荫里的影像可为例证。这种高耸草本植物繁茂叶片间的小空隙,形成随机分布的针孔,而每个针孔在地面投射出一轮食日。这幅影像摄于浦纳当地最食分(食甚),月亮约遮掩60%的太阳直径之时。 不过在月球黝黑的影子,掠过非洲中部、南亚和中国的狭窄环食带内,食甚阶段可见到月盘镶在明亮日盘内的火之环景观。

此现象可称为小孔成像,即光沿直线传播。
