Other factors that will affect the sky, and are not typically considered, are the presence of natural forms of light pollution, such as the Gegenschein, the zodiacal light, and aurora.
It also was very faint, only about half as bright as the notoriously difficult Gegenschein (counterglow - a bright patch in the zodiacal light, directly opposite to the Sun).
A similar effect is the Gegenschein, which is seen directly opposite to the sun's position in the sky. It is much fainter than the Zodiacal light, and is caused by sunlight reflecting off dust particles outside the earth's orbit.
