Ever wonder what happens to your Globe at Night measurements? Scientists and citizen-scientists are using them in a variety of projects, most of which need multiple data points at the same location over time. This map shows 5,000 locations on Earth where an observation has been made but there hasn’t been a new one in the last five years. Do you or a friend live near one of these points? Help us out by making an observation there! And while you are at it, take a measurement where none have been taken yet! (See the map for 2016 and zoom in to your location to see where data was taken in 2016.)
