This list is the extension of Marsden's list of observatories published in "Minor Planet Circularies". The additional data about observatories were taken from other sources.
ATTENTION! These coordinates may be used for reduction of routinal observations with standard accuracy. For reduction of high accuracy observations (CCD, meridian obs., NEO objects) should be used more exact coordinates of instrument.

ASCII file with the coordinates of observatories has the following format:
| position | contents | comment |
|---|---|---|
| 2- 5 | Number of observatory | The numbers 0-999 were taken in according to Marsden (Ref.1), the numbers from 1000 were appropriated by us. |
| 7-30 | Location of observatory | Country, place, town |
| 32-75 | Name of observatory and some notes | |
| 77-85 | Longitude | in angular units (dddmm.mm) |
| 87-94 | Geodetic latitude | in angular units (ddmm.m) |
| 96-99 | Height in meters | For observatories with numbers 0-999 and code of reference 1* the heights were taken from maps |
| 101-103 | Code of reference | For numbers 0-999 the code equals 1 usually. It should be noted that in many cases the heights were obtained unreal from Marsden's data. So the coordinates of obs. from MPC were improved by us from other sources and the code of these observatories was noted by the asteriks (1*) |
