Lunar eclipse with occultation of Mars
In a total lunar eclipse, the Sun, Earth and Moon are aligned, blocking direct sunlight to the Moon. On December 7, a lunar eclipse was accompanied by an occultation of Mars. Not only were the Sun, Earth and Moon aligned, but Mars was at opposition. That means it was positioned directly between the Sun and the Earth. And since the Moon was also in the alignment for a time, it hid Mars. This is called an occultation.

As in the totality of a solar eclipse, you had to be in the right place at the right time to see the occultation. Tom Glenn was, and here is a photo he took as Mars reappeared. Astronomy Picture of the Day described it:
Quote
In the image Mars appears to rise just over ancient, dark-floored, lunar crater Abel very close to the southeastern edge of the Moon's near side. Humboldt is the large impact crater to its north (left).
