A study of over 40,000 written entries in Irish Annals and ice core measurements shows a strong correlation between the occurrence of volcanic eruptions and extreme cold weather in Ireland over a 1200 year period.
Comet Pan-STARRS
Comet Pan-STARRS, recently discovered by the Panoramic Survey Telescope & Rapid Response System, should be visible in early March 2013 as it approaches the Sun. Key dates are March 5th, when the comet comes closest to Earth (about 100 million miles away), March 10th, when the comet comes closest to the sun, and March 12th and 13th when Pan-STARRS emerges in the western sunset sky not far from the crescent Moon.
