As Mercury rises further from the Sun each day, Saturn is currently sliding into the sunset heading for superior conjunction. The two will pass each other on October 3rd through October 6th. The pair will be closest on October 4th, at a bit over 3° separation. The 5th will see the two quite close at about 3.5° separation. There will be about a magnitude difference in brightness between the two, with Mercury at -0.27 magnitude and Saturn at 0.69 magnitude. At about 15° above the horizon at sunset this will make for a nice pairing in the dusk.
