Defenders of Earth, are you ready to take part?

Ready to start observing Planetary Defense targets with your Unistellar eVscope?

 

Check out our Planetary Defense Campaign page to discover the targets you can observe this month with your eVscope.

Below are two different methods to observe Planetary Defense targets. Scroll down the page to learn more about each method.

  • A. It is in the Unistellar app’s database and you’re observing it via the Science Observation mode
  • B. It is not in the app’s database and you’re observing it via the Science Observation mode

A. The Planetary Defense target is in the Unistellar app’s database

  1. In the Unistellar app, select the Explore tab, enter the name of the asteroid, and tap the Go to button.
  2. Once the Go To is done, select the Science tab and tap on the Planetary defense mode.
  3. Set the Recording parameters according to the instructions for the target on the Campaign page.
  4. Tap LAUNCH to begin the observation.
  5. At the end of the acquisition, a pop-up message will ask for dark frames. Put the dust cap on and press yes.
  6. Please upload your data and submit this REPORT FORM so we know to process your data.

Science mode in the App

B. The Planetary Defense target is not in the Unistellar app’s database

  1. On your smartphone, visit our Moving Target Ephemerides page.
  2. In the Ephemeris Parameters section, select your target and enter the location where you’ll be observing, as well as the date and local time when you’ll be observing. 
  3. Click on Generate to get your results.
  4. After a few seconds, the Ephemeris Results section will be generated with a list of coordinates for the night. Each line corresponds to the position of your target at a specific time.
  5. If your target is visible for your location, you will be able to click on the smartphone icon that will open your Unistellar App and fill the Planetary Defense section with the proper fileds (coordinates and so on). If your target is not visible, a crossed-out eye icon will appear.
  6. The duration, gain and exposure time should automatically be added in the Planetary Defense menu. If not, please use: Gain 25 db, Exposure Time 3971 ms, Duration 10min00s
  7. Once the RA and Dec are filled, tap the Go to button.
  8. Once the Go To is done, select the Science tab and tap on the Planetary defense mode, then tap LAUNCH to begin the observation.
  9. At the end of the acquisition, a pop-up message will ask for dark frames. Put the dust cap on and press yes.
  10. Please upload your data and submit this REPORT FORM so we know to process your data.

For example, if you want to observe your target at 10 PM PST, you should be ready 10 minutes in advance. At 9:50 PM: on the Moving Target Ephemerides page, in the results section, click on the smartphone button associated with the 10 PM time to send the information to the Unistellar App. The Planetary Defense mode on the App will open with the right coordinates and observing parameters. Click on GoTo to point to your target. At 9:58 PM, Launch the recording.
