Tomorrow morning and Monday morning will see a close pairing of Mars and Jupiter. While the two have been moving closer for a few days, during these two dawns the separation will be just under a degree.
Look for the pair to rise about 4:13am, almost two hours before the Sun. The two planets will be 20 degrees above the horizon at sunrise. They should be easy to spot with Jupiter at -2 magnitude and Mars dimmer but still easy at 1.5 magnitude. Look 8° below the pair for Mercury still rising towards maximum elongation.
