Fireworks from the Taurids meteor shower

Posted: 5 November 2012

The Taurids meteor shower is active this month with a double radiant and a double peak and although not one of the major showers in the meteor calendar, it's worth observing with rates of perhaps 5-10 meteors per hour amongst all the artificial fireworks on bonfire night and then a week later.

The Southern Taurids come first on the 5/6 November, with the activity expected to peak around midnight with the radiant lying in western Taurus about ten degrees south of the naked-eye open cluster the Pleiades (M45). The radiant culminates around 12.30am at a decent altitude 54 degrees above the southern horizon but unfortunately a waning, 60 percent illuminated gibbous moon rises around 10pm and will increasingly interfere with watches as the night wears on. The good news is that the tiny fragments burning up in the Earth's atmosphere, debris from the periodic comet 2P/Encke, often produce bright events, fireballs even, and so could punch through the hazy, smoky, moonlit skies. Taurid meteors are also the slowest, with velocities around 25-30 kilometres per second.

The Northern Taurids peak on the night of 12/13 November are are slightly richer than their southern counterpart with a ZHR of 15 as opposed to 10. The radiant lies eight degrees or so further north close to M45 again near Taurus' border with Aries and will culminate at midnight over 60 degrees up. Watches on this night should be more productive as the Moon is new and local skies should be free of all the smoke blighting the Southern Taurids. Coincidentally, November is one of the best months for high sporadic rates, the ever-present background, random shooting stars.

As with observing any meteor shower the best advice is not to stare at the actual radiant but at an altitude of 50 degrees (about the same altitude of the Pole Star from the UK) and 30-40 degrees to one side of shower radiant (the width of a fist held at arm's length is about ten degrees).

November nights can be bone-chilling so be well prepared, especially if you are travelling to a dark site to make your watch. Wrap up well in layers of warm, dry clothing and keeping hands, feet and head warm is essential! Perhaps bring a flask of tea and a snack or two to sustain you if fatigue sets in. Most observers observe from a deck chair or garden lounger and hopefully you won't be so comfortable as to fall asleep! Our greatest ever comet and nova discoverer George Alcock often observed lying on a railway sleeper, the discomfort ensuring he stayed alert but perhaps this is unnecessary this time! If your observing site is a dark one, well away from nearby sources of artificial light then lucky you. If not then try to find a spot where any streetlight or neighbours' security lights are not in your direct vision as it's vital to try to preserve your dark adaption to enable the fainter meteors to be seen. Many people just prefer to observe for fun but if you would like to 'do some science', then check out the advice on the British Astronomical Associations Meteor Section web site at
