MPC Ephemerides for Objects Passing Within Ten Lunar Distances
Note: As a convenience to NEO observers, this form obtains formatted data
      from the IAU Minor Planet Center, which is not associated with A/CC.

Distance         - distances from Earth in lunar distances (LD) at 0000 and 2359 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 2.26 LD

*MPC MPES data for 0600 UTC, July 22nd.
 Other numbers are for 0000-2359 today UTC, processed by A/CC from JPL SSD Horizons data.

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:
none MPC 1-line MPC 8-line
SkyMap (SkyMap Software) Guide (Project Pluto) MegaStar V4.x (E.L.B. Software)
TheSky (Software Bisque)

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.
