Find an exoplanet transit to observe!
Select your region below and choose an event that interests you.
So far, all of our predictions involve Jupiter-size gas giant exoplanets or more massive brown dwarfs. Most of them orbit their stars in less than 10 Earth days, making the exoplanets “Hot Jupiters” because their stars heat them to temperatures over 1600 °C (2000 °F).
Target names starting with “TOI” are new candidate exoplanets from NASA’s TESS space telescope that either need more observations to be confirmed as real exoplanets (and not false signals) or to better measure their orbits. Your observations can help astronomers do this! (TOI stands for TESS Object of Interest.)
Predictions Table explained
- The Link will auto-populate the event’s observing settings into the Unistellar app’s “Exoplanet transits” menu (in the Science tab).
- Note that these links will only work on your smartphone/tablet with the Unistellar app installed.
- Finder is an image of the target field of view (your live view may be rotated by comparison).
- Date is the observation start date in UTC (Universal Time)
- Local is the observation start time in the timezone of your device’s browser.
- eVscope settings are in Exp (exposure time in milliseconds), Gain (in decibels), Cad (cadence in milliseconds), Ra (right ascension), & Dec (declination).
- Click on a row to display the event’s visibility map. Map legend:
- Blue stars & shading = full visibility (you can observe the entire event)
- Yellow triangles = full visibility but some tracking difficulty (when target altitude > 70 degrees)
- Orange diamonds = partial visibility; you may miss the start or end of the event
- No symbol = no visibility (either the target is not up or it is too close to daytime)
