The image at the right shows a portion of the sky centred on the Sun at the instant of greatest eclipse. The Sun's disk is drawn to scale but the extent of the corona depends upon the level of solar activity at the time.

The Sun is in the constellation of Ophiuchus but below it are the bright distinctive stars of the zodiacal constellation of Scorpius, the scorpion, with reddish Antares most prominent.

Mercury was at superior conjunction on 29 November and is still very close to the Sun, only 3.1° away and shining at magnitude −1.1. On the opposite side of the eclipsed Sun is Mars. It is considerably fainter at magnitude +1.6 and is a more distant 18.7° away from the Sun.
