Our October nights begin with the Summer Triangle of Vega, Deneb and Altair high in Britain’s S sky as the Square of Pegasus climbs in the E and the Plough is unmistakable in the NW. By our map times, though, the Triangle has toppled over into the W to be replaced in the S by the Square while the Plough is nearing its familiar autumnal low-point below Polaris in the N.Our October nights begin with the Summer Triangle of Vega, Deneb and Altair high in Britain’s S sky as the Square of Pegasus climbs in the E and the Plough is unmistakable in the NW.

Venus blazes at mag –3.9 to –4.0 well up in the W evening sky as seen from S of the equator. For Britain, though, it is barely 6° high in the SW at sunset at present and sets some 50 minutes later. By the 31st, it is only one degree higher, but stays visible for 80 minutes.Venus blazes at mag –3.9 to –4.0 well up in the W evening sky as seen from S of the equator.

Saturn, low in the SW after Venus sets and darkness descends, shines at mag 0.6 above Antares in Scorpius. To its left, and slightly higher and brighter at mag 0.1 to 0.4, is Mars, which tracks E above the Teapot of Sagittarius, clipping Kaus Borealis, the finial atop the teapot’s lid, on the 7th. As Venus speeds away from the Sun, it passes 3° S of Saturn on the 30th.Saturn, low in the SW after Venus sets and darkness descends, shines at mag 0.6 above Antares in Scorpius.

Catch the Moon 4° above-right of Venus on the 3rd, 6° above-left of Saturn on the 6th and 7° above Mars on the 8th. As the full moon following September’s harvest moon, folklore dictates that the one on the 16th is the hunter’s moon. Two nights later, on the 18/19th, the Moon hides several stars in the Hyades cluster as it approaches Taurus’s leading star Aldebaran, and eventually occults Aldebaran itself for watchers in the USA SE of a line from the Great Lakes to Los Angeles.Catch the Moon 4° above-right of Venus on the 3rd, 6° above-left of Saturn on the 6th and 7° above Mars on the 8th.

Mercury shines brightly very low in the E before sunrise early in the month, but its apparition is almost over by the 11th when it stands only 0.8° above-left of Jupiter as the latter emerges from the Sun’s glare. Jupiter is conspicuous at mag –1.7 and well up in the ESE before dawn by the 28th, when it lies below the impressively earthlit Moon.Mercury shines brightly very low in the E before sunrise early in the month, but its apparition is almost over by the 11th when it stands only 0.8° above-left of Jupiter as the latter emerges from the Sun’s glare.

The Orionids meteor shower is active during the morning hours from the 16th and peaks from the 21st to 24th. Its swift meteors, many leaving trains in their wake, derive from Halley’s comet and diverge from a point to the NE of Betelgeuse in Orion’s shoulder.The Orionids meteor shower is active during the morning hours from the 16th and peaks from the 21st to 24th.
