Mars is closing on Jupiter: watch the gap shrink to 1.2° by November 16
Two bright planets are up before dawn right now, and the gap between them shrinks every morning for the next month. This morning Mars and Jupiter are 12.7° apart, a bit more than a fist held at arm’s length. By the morning of November 16 that gap is down to 1.19°, a little over two full-Moon widths. Closest approach is around 02:00 UT on the 16th, which is 04:00 in Cyprus, with both planets riding high in the south-east. You don’t need any equipment for this one. Pick a morning each week, note how far apart the two points are, and watch Mars catch up. Binoculars add Jupiter’s moons.
