    • You may find the Julian day using either NASA tables or the NASA JPL Web site. There is also a simple computer program for computing the Julian day here.
    • If you wish to check your final answer, go outside around dusk and see if Mars is where you predicted it would be. For a more precise check, visit the NASA Jet Propulsion Laboratory HORIZONS System
      • Change the Target Body to “Mars”
      • Change the Observer Location to “Washington (USNO) DC”
      • Change the Time Span to include Dec. 6, 2018, and set the calculation interval to 10 minutes.
      • Under Table Settings, change “angle format” to “decimal degrees”
      • Click the “Generate Ephemeris” button. Look for the line that reads “2018-Dec-06 00:50” and check the R.A. and DEC. against your right ascension and declination. They won't match exactly, since JPL's calculation is more precise than yours, but it should be close.
