Venus continues to shine as the bright Morning Star in the east-southeast before sunrise. It is moving eastward compared to the stars in Virgo. The planet rises about 2 hours, 40 minutes before sunrise. This morning it is 4.3° to the left of the star Spica.
By 45 minutes before sunrise, bright Mercury is over 13° to the lower left of Venus. This speedy planet rises about 90 minutes before sunrise.
Mercury is making its best morning appearance before sunrise. The planet is rarely visible in a dark sky and almost always during morning twilight or evening twilight.
During the autumn months before sunrise, the plane of the solar system is highly inclined to the horizon so that Mercury is easier to observe. The same occurs during the evening hours of springtime. The planet had a fine appearance during late May 2020.
Detailed note: One hour before sunrise, brilliant Venus is over 16° in altitude in the east-southeast, 4.3° to the left of Spica. Among the dimmer stars of Virgo, Venus is 0.7° to the upper right of 82 Virginis (82 Vir, m = 5.0). The Venus – Mercury gap is 13.4°. Fifteen minutes later, Mercury is about 7° up in the east-southeast.
