September 15th, 2015
For the past few months there’s been an absence of visible planets in the evening and pre-dawn skies; fortunately, that’s about to change. Jupiter is now slowly escaping the glare of the Sun’s light and is edging over the pre-dawn eastern horizon.
There it joins Mars and Venus as they dance around the constellation of Leo, the Lion. Observers in North America may get the best view of the planets while those in Australia might find it difficult to see anything but Venus. Wherever you are, Jupiter may be a challenging sight and you’ll need a good, unobstructed view of the horizon to stand a chance of spotting it. Using binoculars will also certainly help.
