Export selection to your calendar

To find out if you can observe an exoplanet transit, simply select a row and zoom by scrolling on the map. If you are near any location with a symbol, you are qualified for that scientific mission! If there is not a symbol near your location, you will not be able to observe the event. 

Each symbol has a meaning:

  • Blue stars & shading = you can observe the entire event.
  • Yellow triangles = you can observe the entire event but you may have tracking difficulty due to the altitude of the star above your horizon.
  • Orange diamonds = you may miss the start or end of the event.

You can click on any symbol for precise local observation times, target altitudes, and Sun altitudes.

Reading the Prediction Table:

  • The Link automatically populates observing settings into the Unistellar app’s “Exoplanet transits” Science menu.
  • Finder is an image of the target field of view. It may be rotated in your sky. 
  • Date is the observation start date in UTC (Coordinated Universal Time)
  • Start, End UTC is the event’s observation start or end time in UTC. Your local start or end time may differ.
  • Local is the observation start time in the time zone of your device’s browser.
