During the coming early evenings, Mercury and Venus will be performing a dance in our western sky. They will appear within 1° of each other this month from the 8th through 12th. They will appear closest during the evening of January 10th with a separation of only 38 arcminutes. Below is a chart I created to illustrate how Mercury and Venus will be appearing in Chicago's western sky at 17:30 CST during the coming evenings. Photos and descriptions of the pair would be welcome additions to this thread.
