Sample Ephemeris

Below is a sample of what an ephemeris looks like. This one was generated by the JPL HORIZONS system. Going through the options,
-- the Target Body is 103P/Hartley 2,
-- Observer Location is city = College Park (location of the University of Maryland),
-- Time Span was the 1-30 Nov 2010 UT, every hour,
-- Table Settings, I selected Astrometric RA & DEC (1), Airmass (8), Vis mag. & Surf Brt (9), Sun-Target-Obsrvr angl (aka phase)(24), and Constellation ID (29). (I sometimes also use options 19 and 20 if I want to know how far my target is from the sun and from me and how fast it is moving relative to the sun and me.)
-- Finally, in the Optional observer-table settings, I also selected the "skip daylight" option and gave an "elevation cutoff" of 5 degrees (ie, I can't see it during the day or if it's below the horizon).
Then I'm ready to "Generate Ephemeris." Follow the instructions to generate an ephemeris for your observing location and the nights you are observing.

Check the Charts page to get additional ephemerides.

Column meaning:
 
TIME

  Prior to 1962, times are UT1. Dates thereafter are UTC. Any 'b' symbol in
the 1st-column denotes a B.C. date. First-column blank (" ") denotes an A.D.
date. Calendar dates prior to 1582-Oct-15 are in the Julian calendar system.
Later calendar dates are in the Gregorian system.

  The uniform Coordinate Time scale is used internally. Conversion between
CT and the selected non-uniform UT output scale has not been determined for
UTC times after the next July or January 1st.  The last known leap-second
is used over any future interval.

  NOTE: "n.a." in output means quantity "not available" at the print-time.
 
SOLAR PRESENCE (OBSERVING SITE)
  Time tag is followed by a blank, then a solar-presence symbol:

        '*'  Daylight (refracted solar upper-limb on or above apparent horizon)
        'C'  Civil twilight/dawn
        'N'  Nautical twilight/dawn
        'A'  Astronomical twilight/dawn
        ' '  Night OR geocentric ephemeris

LUNAR PRESENCE (OBSERVING SITE)
  The solar-presence symbol is immediately followed by a lunar-presence symbol:

        'm'  Refracted upper-limb of Moon on or above apparent horizon
        ' '  Refracted upper-limb of Moon below apparent horizon OR geocentric
             ephemeris
 
 R.A._(ICRF/J2000.0)_DEC =
   J2000.0 astrometric right ascension and declination of target center.
Corrected for light-time. Units: HMS (HH MM SS.ff) and DMS (DD MM SS.f)
 
 a-mass =
   Relative optical airmass at target center point. Topocentric EARTH sites,
ABOVE HORIZON ONLY.  Unitless.
 
 T-mag N-mag =
   Comet's approximate apparent visual total magnitude ("T-mag") and nuclear
magnitude ("N-mag") by following definitions:
   T-mag =  M1 + 5*log10(delta) + k1*log10(r)
   N-mag =  M2 + 5*log10(delta) + k2*log10(r) + phcof*beta
Units: none
 
 S-T-O =
   Sun-Target-Observer (~ PHASE ANGLE) angle: the vertex angle at target center
formed by a vector to the apparent center of the Sun and a vector intersecting
the observer at print-time. This measurable angle is within 20 arcseconds
(0.006 deg) of the reduced PHASE ANGLE at observer's location at print time.
The difference is due to down-leg stellar aberration affecting measured target
position but not apparent solar illumination direction.  When computing phase,
Horizons uses the true phase angle, not S-T-O, but the resulting difference
in illuminated fraction is less than 0.001%.
   Units: DEGREES

 
 Cnst =
   Constellation ID; the 3-letter abbreviation for the name of the
constellation containing the target center's astrometric position,
as defined by IAU (1930) boundary delineation.  See documentation
for list of abbreviations.
