GLOBE at Night 2011 Observation Dates Announced
GLOBE at Night is an annual citizen-science campaign that encourages people all over the world to record the brightness of their night sky. For two weeks in late February/early March, when the Moon is not out during the early evening and the constellation of Orion can be seen by everyone everywhere, children and adults match the appearance of Orion with 7 star maps of progressively fainter stars found on www.globeatnight.org They then submit their measurements (e.g., which star map they chose) on-line with their date, time and location.
Through GLOBE at Night, students — alongside teachers, parents and community members — are amassing a data set from which they can explore the nature of light pollution locally and across the globe.
February 21 – March 6, 2011, Northern and Southern Hemispheres (using Orion)
March 22 – April 4, 2011, Northern Hemisphere (using Crux or Leo).
March 24 – April 6, 2011, Southern Hemisphere (using Orion)
