GLOBE at Night, now in its 6th year, encourages astronomers and citizen-scientists worldwide to record the brightness of the night sky to help create a global map of light pollution. During two weeks of moonless evenings, observers compare the appearance of a constellation (Orion in February/March and Leo or Crux in March/April) with the view depicted on seven charts showing progressively fainter stars. They then go online to report their date, time, location, and the number of the chart that best matches their view of the constellation. New this year: Observers with smart phones or tablets can submit their measurements from the field in real time!
