Distance         - distance from Earth in lunar distances (LD) at 0000 and 2400 today
Visibility today - if available, JPL geocentric apparent magnitude and solar elongation - shows min-max, not trend
                   (note that JPL Horizons provides nil V magnitude for elongation < 60°)
Earth closest    - Earth passage distance at best date-time calculation UTC
Moon closest     - lunar passage, calculated only if Earth passage is under 2.2 LD

*MPC MPES data for 0600 UTC, Feb. 4th.
 Other numbers are for 0000-2400 today UTC, processed by A/CC from JPL SSD Horizons data.



      Options:

Start date for ephemerides:  Number of dates to output 

Ephemeris interval:   Ephemeris
units:  days   hours   minutes   seconds

For daily ephemerides, enter desired offset from 0h UT:  hours

Observatory code: 

Display positions in: truncated sexagesimal or
 full sexagesimal or
 decimal units

	

 Total motion & direction
 Separate R.A. & Decl. sky motions
 Separate R.A. & Decl. coordinate motions

Display motions as:  "/sec   "/min   "/hr   °/day

	

Suppress output    if sun above local horizon    if object below local horizon

 Generate perturbed ephemerides for unperturbed orbits

Also display elements for epoch 


Format for elements output:

If you select 8-line MPC format, you may display the residual block for the objects selected:

 Show residuals blocks.Show only residual lines containing observations from code .
If you select 8-line MPC format the elements will be displayed with the ephemerides.
If you select any format other than 8-line MPC format, only the elements are returned.
In such cases your browser should download the elements file and save it
to your local disk.
