Tonight the skies will be witness to a Supermoon or Large Full moon. Tonight's full moon will appear 14% larger and 30% brighter than usual. A supermoon occurs when the moon hits its full phase while also making its closest approach to Earth for the month, called a perigee. The moon will be within 221,802 miles(356,955.72 km) of Earth — its closest approach of the year.
The most recent supermoon, in March 2011, was the biggest and brightest full moon in 18 years.
David Kriegler of the University of Nebraska said "there have been about 12 supermoons since 1954, or about one every five years"
So why not step outside and enjoy the spectacular sights in the sky tonight!

THE QUALITY OF bathing water in Ireland improved between 2010 and 2011, a new report shows. Minister for the Environment, Community and Local Government, Phil Hogan, TD welcomed the publication of the Environmental Protection Agency’s (EPA) The Quality of Bathing Water in Ireland overview for 2011.
The report noted that there was a net decrease of six locations complying with the higher ‘guide’ standard.
The results for the 2011 bathing season show that overall, the quality of bathing water in Ireland improved in comparison with the 2010 equivalent. Overall, 98.5 per cent (133 out of 135) of bathing areas complied with the EU mandatory standard, equating to ‘sufficient’ water quality. This is the highest number complying with the EU mandatory standard since 2000.
83 per cent (112 bathing areas) achieved the higher guide standard, equating to ‘good’ water quality.
In 2011, five new beaches were identified and the number of designated bathing waters increased for the first time in Ireland in 10 years, rising to 135.
In 2011 the Bathing Water Quality Regulations, which were introduced in 2008, become operational.
Minister Hogan said Ireland will have to redouble its efforts to maintain and improve bathing water quality standards. The stricter criteria in the higher guide standard requires local authorities to make extra efforts to improve the water quality and to tackle any potential sources of pollution.
