The Globe at Night citizen science project needs to be done on the nights of the New Moon, approximately 1.5–2 hours after sunset. For the November campaign, those nights correspond to the dates Friday, November 13th, and Saturday, November 14th.

Before you go out, use a star map (download Bell Star Map here) or a night sky app on your phone to get a good idea where the constellations will be in the sky above you. The November constellations for the Globe at Night campaign are Pegasus and Perseus.

You only need to report one constellation per submission. Once you find out where to look for the constellation you want to report, head outside with your smart device.

Go to the Globe at Night Report page to start to enter Globe at Night measurements. Try to launch this page before you go outside, and make sure you are in the “Nighttime version”.

  1. With a smartphone, the app will put in the date, time, location (latitude/longitude) automatically. Otherwise please type them in. In the location comment box, type the street address closest to your observation along with the city, state or province, and country. Also, add MN Statewide Star Party.
  2. Choose the star chart that looks most closely to what you see toward your constellation. That is, what is the faintest star you can see in the sky and find in the chart?
  3. Choose the amount of cloud cover at the time of observation and then click on the “SUBMIT DATA” button.

That’s it! Encourage your friends and family around town to participate in this simple citizen science project. Our goal is to set a record for the most number of Globe at Night submissions from any state across the country!
