Last NEOCP/PCCP objects

All columns should be sortable by clicking them (Java Script must be allowed).
The time for creating this site is  2021-02-28 23:13:00 ME(S)Z.
The time of last data from MPC is 2021-02-28 23:05:44 ME(S)Z.

At moment the middle European Time zone (MEZ) or summertime zone (MESZ) is used for the times above. Sorry for the inconvenience with this problem. All other times are UT.

Source: Text of MPC with links of Project Pluto.

Green colored lines may have an impact or a satellite start on Earth (see Link in Design. column). Orange colored values are getting better. Red-colored values are getting worse. Bold values are interesting for smaller instruments and in the northern hemisphere.

Other sites: CFA 1, CFA 2, and Scout.

How to read the table? The objects from the NEOCP list has often very short arcs. So the uncertainty outside the observed arcs raised fast if the content of the column 'obs arc' is very low. All arcs lower than 0.1 days are mostly in very uncertain orbits and so all other values may be false. At first, take a look at the ephemeris by Bill Gray with a click at the value in column 'Design'. At the ephemerides section at this link (at the end) you find the column 'sig'. It's in arcseconds. But if it's given in 'd' (degrees), the orbit is very unsure or completely random. If it's given in ' (arcmin), there is a chance, that you or another can find it and nail down the orbit. You can play now with the other columns in the table below, to learn about the objects or plan, what object you can observe. The columns are explained at the bottom of this page. The five columns Δmin etc. are calculation, I made with find_orbit to find out if the object was or will be at the nearest point to the Earth. But take also the look at the 'ob arc', otherwise, you can be fooled by the values. If find_orbit failed, these values are blank. Have fun and donate at Paypal!

Explanations:

  • No: running number. Link is the extensive analyse at CNEOS
  • Design.: NEOCP designation of the object. Link is the Orbit solution and ephemerides by Bill Gray (Project pluto).
  • Sc.: Score of object (maximum 100%).
  • Discovery: Date of discovery (UT).
  • R.A.: Right Ascension (J2000.0) for time at top of table. May be bad, if orbit is bad. Link is the ephemerides at MPC. Please note, that MPC kills the link in this link, so you cannot go to the scatter diagrams and orbit solution at right of each line (if available).
  • Decl.: Declination (J2000.0) for time at top of table. May be bad, if orbit is bad.
  • Elo: Elongation in degrees. May be bad, if orbit is bad.
  • Δ: Distance of object to Earth in AU. May be bead, if orbit is bad.
  • Δmin: Lowest distance of object to Earth in AU. Green, if in the past. Red, if in the future. May be bad, if orbit is bad.
  • Tmin: Time of lowest distance to Earth in AU (without year, year is is next 6-month range of date). Green if in the past and red, if in the future. May be bad, if orbit is bad. Linked to daily ephemeris.
  • Elom: Elongation at the time of lowest distance to Earth in degrees. Green if in the past and red, if in the future. May be bad, if orbit is bad. Linked to hourly ephemeris.
  • Magm: Magnitude at the time of lowest distance to Earth in magnitudes. Green if in the past and red, if in the future. May be bad, if orbit is bad. Linked to minutely ephemeris.
  • Motm: Motion at the time of lowest distance to Earth in arc seconds per minute. Green if in the past and red, if in the future. May be bad, if orbit is bad.
  • r: Distance of object to sun in AU. May be bead, if orbit is bad.
  • V: Magnitude V dor time at top if table. May be bad, if orbit is bad.
  • Ch.: Change of last entry (add is addition and upd is update).
  • Time(UT): Time of last entry (not the time for ephemeris values).
  • Obs.: Number of observations. Link is the observations listing at MPC.
  • Obs arc: Arc of observations in days.
  • H: Absolute magnitude. May be bad, if orbit is bad.
  • D: Approximate diameter in meter.
  • Last: Time since last observation in hours.
  • Motion: Motion in arc seconds per minute. May be bad, if orbit is bad.
  • PA: Position angle in degrees of motion. May be bad, if orbit is bad.
  • Orbs: Number of morbit solution (1 orbit means a reasonable good orbit, more orbits get worse). Link is the orbits listing at MPC.
  • Unc: Acttual uncertainty in sky positions from MPC data in arc minutes. Link goes to the actual MPC scatter map.
  • PA: Actual position angle of above uncertainties in degrees. Link goes to the MPC offset listing for the orbits.
  • Sig 1: Current ephemeris uncertainty from ProjectPluto data in arc minutes. These data are mostly lower than the MPC data. Link goes to the corresponding actual MPC scatter map (this show mostly other values as this ProjectPluto value).
  • Sig 2: Ephemeris uncertainty in 2 days from ProjectPluto data in arc minutes. These data are mostly lower than the MPC data. Link goes to the MPC scatter map in 2 days in the future (this show mostly other values as this ProjectPluto value).
  • Fac: Factor of Sig 1/Sig 2. Bigger is more worse.
  • Diff.: Difficulty as relative number. Depending from magnitude and motion. Better CCD may have lower values for fast objects. If uncvertainty high, the factor is also rising to cover the search area. Geocentric, no altitude etc. used
  • U: Certainty of orbit. Smaller is better.
  • Res.: Mean resolution of all observations in arc seconds.
  • q: Perihelion in AU. May be bad, if orbit is bad.
  • a: Great half axis in AU. May be bad, if orbit is bad.
  • Q: Aphelion in AU. May be bad, if orbit is bad.
  • e: Eccentricity. May be bad, if orbit is bad.
  • i: Inclination. May be bad, if orbit is bad.
  • MOID: Minimal orbital intersection distance (Earth) in AU. May be bad, if orbit is bad.
  • Obj.: Object (ast for asteroid and cmt for comet).
  • St.: Number of stations, which observed the orbit. More than one stations means, that the object is no fake.
  • Stats: List of stations, which observed the object.
