The skies over Kendal in October

We’re moving into the darker, colder and usually rather cloudy nights of the end of the year. As ever, this post is illustrated with a few sky charts showing midnight on the first, last and fifteenth day of the month. The dots represent brighter stars, green circles are star clusters, nebulae, galaxies and the like and the very brightest stars, the Moon and the planets are named when they appear. Sky charts provided using Stellarium.

Solar system

The Moon will be in the last quarter phase on the 1st, new on the 7th, first quarter on the 14th and full on the 23rd. On the 14th, the Moon will occult the star 50 Sagittarii at around 8:10pm for northern observers.

The middle of the month sees the start of the Orionid meteor shower, which will peak on the 21st. Peak rates are low and a full Moon will blot out all but the brightest. Orionids are fast and leave persistent trails. They are best seen before dawn.

Heavens above presently lists two comets above magnitude 12 and seven asteroids above magnitude 10 in the hours of darkness. The comets are: 103P Hartley at 5.6 – approaching visibility – in Cassiopeia and 10P Tempel 2 at 10.1 in Cetus. Details on the future movements and changing brightness of the comets can be found here. The asteroids are 6 Hebe at 7.8 in Cetus; 4 Vesta at 7.9 in Virgo; 8 Flora at 8.6 in Aquarius; 1 Ceres at 8.9 in Sagittarius; 7 Iris at 9.4 in Gemini; 39 Laetitia at 9.5 in Aquarius and 471 Papagena at 9.8 in Cetus – rather a busy constellation this month.

The Planets

Mars is usually lost in atmospheric haze now. It shines at +1.5, appearing in the south-west, only to set an hour after the Sun.

Venus is seen just below Mars as the Sun sets, shining much brighter, but also lower, requiring a very low horizon to the West to see it.

Mercury for the next day or two, Mercury is visible in the Eastern horizon shortly before the Sun rises, though it will appear dimmer than its +1.3 magnitude suggests due to the bright sky around it.

Saturn returns to the skies at the end of the month, making an appearance shortly before dawn with rings now angled such that they look more like rings. The planet will shine at a magnitude of 0.7.

Jupiter continues to shine brightly as ‘that star in the East’. It shines at a magnitude of -2.9 and is in an empty part of the sky. Its inclination is such that transits of satellites happen quite a bit. Times of some of these and appearances of the Great Red Spot are here.

Uranus lies a couple of degrees west of Jupiter, plus a little above, and shines at 5.7.

Neptune is also in the morning skies, on the border of Capricorn and Aquarius.

A few things outside the solar system

The constellations of Leo, Virgo and the Big Dipper are all home to galaxies, details here. This is not a good month to look at faint things as the all-night twilight obliterates detail and contrast.

The Usual Stuff

If you want to watch satellites flaring or passing in the sky (even sometimes during the day), then go to Heavens Above to get times and directions. If you need assistance in deciding where things are in the sky, why not install the free program Stellarium, which does all the work for you? Finally, to avoid the dreaded clouds, Met Check gives a quick forecast and the Met satellites or other satellites can be used to track breaks in the cloud. For an indication of auroral or solar activity, SpaceWeather.com is an invaluable resource. If the stars aren’t available, there’s always solar astronomy. Projections of the Sun onto white card can show sunspots, when properly focused. A good filter (not an eyepiece filter) or a dedicated solar telescope will show better details. Never observe the Sun without filters and never with an inadequate, inappropriate or old (and therefore possibly with holes in) filter.

Public events

For young astronomers (ages 9-16) Space Explorers is run in Kendal Museum on the third Saturday of most months from 2:30-4:00 pm. The next meeting is on Saturday the 23rd. The Society for Popular Astronomy also has a sky map for young astronomers here.

Plus why not pop along to the Eddington Society, which meets at Kendal Museum on the first Monday of each month, this month it is on the 4th, with member’s projects the subject of the meeting. There will also be a public observing event at The Brewery Arts Centre on the 15th from 6:30pm.
