Calling all amateur star-gazers- help map light pollution during national Star Count Week 20-27 January

Count the stars


Rural campaigners and astronomers are looking to recruit amateur star-gazers to help them map light pollution during their national Star Count Week 20-27 January


The Campaign to Protect Rural England (CPRE) and the British Astronomical Associations Campaign for Dark Skies (CfDS) are asking people to take part in the 2012 Star Count Week.


Star gazers are asked to count the number of stars they can see within the constellation of Orion. The results will help create a 2012 Star Count map, illustrating how light pollution is affecting the view of the night sky across the UK.


Emma Marrington, Rural Policy Campaigner at CPRE, says: Light pollution may not seem to be the most serious environmental issue, but it has a range of significant impacts. It damages the character of the countryside, blurs the distinction between town and country, and denies people the experience of a dark, starry sky. Light pollution can disrupt wildlife and badly affect peoples sleeping patterns.


Information gathered during the 2011 Star Count week last January showed that the proportion of people taking part in the survey who are living with severe light pollution increased from 54 per cent in 2007 to a new high of 59 per cent. Only eight per cent of participants could see more then 20 stars and just one per cent of people had truly dark skies, seeing 30 or more stars.


Bob Mizon, Campaign for Dark Skies Coordinator, says: The Star Count survey will help us measure the extent of light pollution. We want to use this evidence to convince Ministers and local councils of the need to take action to tackle it, for example by ensuring that the correct lighting is used only where it is needed and when it is needed. This would cut light pollution, reduce carbon emissions and save money at the same time.


Recently, more local authorities have been seeking ways to deliver their services more efficiently, and there is also growing awareness of the impact of poorly designed street-lighting. Switch off or dimming schemes for lighting, in consultation with the police and local people to ensure that there are not adverse impacts on safety, can be effective. Redesign of lighting to ensure it is better targeted on where it needs to be also saves energy, money and our long-term view of the night sky.


It is simple and easy to take part in Star Count Week 2012 and people can sign up for an email reminder to take part. Full instructions are available on the CPRE website www.cpre.org.uk/starcount.


How to take part in Star Count Week 2012:


Participants can choose any night between Friday 20 January and Friday 27 January but the sky must be clear, with no haze or clouds, so there is the best chance of seeing stars. It is recommended that observations are made after 7pm so the sky is sufficiently dark.


Organisers are asking people to count stars within the constellation of Orion in the south western night sky. The main area of the constellation is bounded by four bright stars. The star count should not include these four corner stars only those within this rectangular boundary but do include the stars in the middle known as Orion's three-star belt. (A diagram is available at www.cpre.org.uk/starcount)


People should make a count of the number of stars seen with the naked eye (not with telescopes or binoculars) and then simply complete the online survey form: https://www.surveymonkey.com/s/starcount-2012 or send their count, the time and date it was made, and the location to our address: Star Count, Campaign for Dark Skies, 38 The Vineries, Colehill, Wimborne, BH21 2PX.
