Roving observer file. This contains "MPC codes" for observers who don't have MPC codes, mostly satellite observers. They could be handled using code 247 (Roving Observer), or using the XXX code (see below for details), but it can be more convenient if they have their own codes. Locations can be in the MPC standard longitude/rho_cos_phi/rho_sin_phi triplet format, or as lon/lat/altitude. So far, MPC has used codes with starting characters 0-9 or A-Z, followed by two digits. So I've used three letter codes, often mixed-case, ideally giving a hint as to the observatory. One is not limited to alphanumerics; note the use of '2.2' and '0.6' for the Mauna Kea 2.2-meter and 0.6-meter scopes. Characters from ASCII 33 = '!' to 126='~' can be used, for 94^3=830584 possible observatory codes. That should last for a while. The '!' in column 5 indicates that the data depart from the usual MPC format. The observatory name starts in column 48, rather than column 31, to allow more precision. It also gives room to specify a non-Earth based observer (see examples below for planets, MSL, LCROSS impact point, etc.) It allows for four-character MPC codes. Punched-card format astrometry won't support that, but ADES will, and some of my software allows one to request (for example) ephemerides from a four-character "MPC code". I may support such codes by allowing 81-column astrometry, though that would force us to abandon punched cards. Longitudes and latitudes are either in decimal degree or deg/min/sec form. See, e.g., (273) EISCAT for an example of the latter. East and North are positive. For West 82.3 degrees, you could use either -82.3 or 277.7 (implied east), or 2774200. or -821800. Altitudes are in meters above the (WGS84) ellipsoid. The difference between ellipsoidal altitudes and above sea level altitudes can be up to about 100 meters. Gareth Williams tells me that MPC has been careful about asking people which flavor of altitude they're using. If they give an ASL elevation, he corrects it to an ellipsoidal one using the EGM96 model. Google Earth altitudes are ASL and therefore always corrected; GPS positions have to be flagged so that MPC can know whether to correct them. Any line starting with a space is assumed to be a comment. Negative longitudes (and those between 180 and 360) are in the Western Hemisphere. NOTE that rather than add codes here, one can use code (247), the "roving observer", as described at https://www.minorplanetcenter.net/iau/info/RovingObs.html _Or_, one can use code (XXX), as described at https://www.minorplanetcenter.net/iau/info/Astrometry.html#HowObsCode For this last, one uses code XXX, and inserts a line at the top of the observations such as COM Long. 239 18 45 E, Lat. 33 54 11 N, Alt. 100m, Google Earth Note that MPC is rather strict about the above format (east longitudes only, degrees/minutes/seconds). Find_Orb is more flexible -- you can use any "code", meaning you can even move existing codes, and you can use decimal degrees and West longitudes if you wish -- but don't expect MPC to understand what you've done.

Some are not very close to the position specified for (568) (see http://arxiv.org/pdf/1106.5835 for an example where the difference matters -- admittedly unusual, involving a close-in artificial object) and in any case, it's sometimes convenient for an observatory code to tell you exactly which scope was used. The following list is from: http://irtfweb.ifa.hawaii.edu/IRrefdata/telescope_ref_data.php, and/or http://www.ifa.hawaii.edu/mko/coordinates.shtml (same data). I had doubts about these lat/lon/alts, derived from an aerial survey and in NAD83 datum, with altitudes in feet (data given in non-metric units always makes me worry) and given to a meaningless precision of about 0.3 millimeters -- those sorts of mistakes usually mean bogus data -- but checks with people who have actually been on Mauna Kea with GPS units have assuaged those worries. Lat/lon/alts in this file are supposed to be on the WGS84 ellipsoid. I just took the NAD83 lat/longs and ignored the difference (about two meters). I increased altitudes by 26 meters, the approximate geoid height given by https://geographiclib.sourceforge.io/cgi-bin/GeoidEval?input=19.82528+-155.46887&option=Submit to convert heights above sea level (or, equivalently, above the geoid) to heights above the WGS84 ellipsoid. No altitudes were given for JCMT and CSO. 4190 meters (increased by 26 meters) seemed at least roughly in the ballpark of the altitudes for the other telescopes. Note also that the MPC position for (568) corresponds to longitude -155.4722, lat 19.8262, 4202 meters. After allowing for roundoff (only five digits on parallaxes!), this looks like the correct position for IRTF. longitude latitude height DDDmmss.sssss DDmmss.sssss (m) 0.6 !-1552815.46587 +194917.81149 4212.327 Univ of Hawaii 0.6-m, Mauna Kea 2.2 !-1552809.96073 +194922.76784 4239.555 Univ of Hawaii 2.2-m, Mauna Kea CFH !-1552807.95258 +194930.90648 4230.106 Canada-France-Hawaii Telescope, Mauna Kea (CFHT) IRT !-1552819.19564 +194934.38594 4194.067 Infrared Telescope Facility (IRTF) UKI !-1552813.17630 +194920.75334 4224.498 UK Infrared Telescope (UKIRT) JCM !-1552837.20394 +194922.10741 4216 James Clerke Maxwell Telescope (JCMT) CSO !-1552831.78945 +194920.77658 4216 Caltech Submillimeter Observatory (CSO) Ke1 !-1552828.98665 +194933.40757 4185.581 Keck 1, Mauna Kea Ke2 !-1552827.24268 +194935.61788 4185.581 Keck 2, Mauna Kea Sub !-1552833.66719 +194931.81425 4189.001 Subaru, Mauna Kea Gem !-1552808.56831 +194925.68521 4239.439 Gemini North, Mauna Kea The following five (official) MPC sites have corrected positions, copy/pasted from the above. 266 !-1552833.66719 +194931.81425 4189.001 New Horizons KBO Search-Subaru 267 !-1552807.95258 +194930.90648 4230.106 New Horizons KBO Search-CFHT T09 !-1552833.66719 +194931.81425 4189.001 Mauna Kea-UH/Tholen NEO Follow-Up (Subaru) T12 !-1552809.96073 +194922.76784 4239.555 Mauna Kea-UH/Tholen NEO Follow-Up (2.24-m) T14 !-1552807.95258 +194930.90648 4230.106 Mauna Kea-UH/Tholen NEO Follow-Up (CFHT) Ce1 ! -2.566025 +37.982840 1532 Centu1 (J75 scope) At one time, it looked as if there might be some Dawn-based astrometry, with coordinates relative to Ceres.

(J95) is at a _geoid_ height (from Google Earth) of 105 metres; this was misinterpreted as an _ellipsoid_ altitude in the MPC's file. The following will override that mistake, adding in the 47.6-m geoid height for Peter's location. (MPC has fixed this. But the following coordinates are more precise, and Peter observes a lot of artsats, where the added precision matters.)
