Enter desired ephemeris parameters for [[ currentObj ]]

By default, a geocentric (code=500) ephemeris is generated at the current time with no limiting magnitude and no field-of-view (FoV) constraint. FoV center fields (RA and Dec) are only valid for single-time ephemerides. Start and stop time must be within 30 days of current time. For a multi-time ephemeris, the Stop Time and Time Step must be selected to ensure no more than 100 steps are requested.

Select Ephemeris Type Multi-time Single Time

Start Time (UTC): Enter appropriate UTC date and optionally time (YYYY-MM-DD [hh[:mm[:ss]]]).

Stop Time (UTC): Enter appropriate UTC date and optionally time (YYYY-MM-DD [hh[:mm[:ss]]]).

Time Step:

Observatory Code: Enter appropriate observatory code. Should be MPC 3-character string: e.g. 'G96'.

Limiting magnitude: Magnitude must be a number from 1 to 40.

FoV diameter ('): FoV Diameter must be a positive-definite number less than or equal to 1800 arc-minutes.

FoV center RA: FoV RA must be either decimal degrees (between 0 and 360) or hours, minutes, seconds (hh:mm:ss[s])

FoV center Dec: FoV Dec must be either decimal degrees (between -90 and 90) or deg., arc-min., arc-sec. (dd:mm:ss)
