An Almost Eclipse of the Moon

Explanation: This composited series of images follows the Moon on January 10, the first Full Moon of 2020, in Hungarian skies. The lunar disk is in mid-eclipse at the center of the sequence though. It looks only slightly darker there as it passes through the light outer shadow or penumbra of planet Earth. In fact during this penumbral lunar eclipse the Moon almost crossed into the northern edge of Earth’s dark central shadow or umbra. Subtle and hard to see, this penumbral lunar eclipse was the first of four lunar eclipses in 2020, all of which will be penumbral lunar eclipses.

说明：这个组合影像系列，呈现1月10日悬在匈牙利上空的2020年头个满月。而在这个影像系列中间的月盘，则记录了一次月食的中点。不过它只是稍暗一些，因为月盘刚好穿过地球影子淡灰色的外围半影。在这次的半影月食期间，月亮几乎接触到地球黝黑暗影中心的本影之北缘。隐约且难以察觉的这个半影月食，是2020年4次月食（全是半影月食）的首例。
