Visibility - apparent magnitude & solar elongation at 0600 UTC on March 18th
           - V > 22.0 is out of view for most observers & V > 24.4 is out of view for almost everyone else
           - el. < 60.0° is leaving view for many observers & el. < 40.0° is out of view for everyone
Arc        - the longest observing arc (in days) used by either risk monitor for its risk analysis
VI#1       - the year with the earliest virtual impactor solution currently listed by either risk monitor
Last news  - last day UTC on which A/CC had news to report about this object's risk assessment
Cum. prob. - highest cumulative probability calculated for Earth impact (1.0/1.0e-06 = "one in a million")
TS         - highest Torino Scale rating reported by either risk monitor for this object
PS cum.    - highest Palermo Scale cumulative rating reported by either risk monitor
PS max.    - highest Palermo Scale maximum rating reported by either risk monitor

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.
