4.10. Unidentified objects

In this list there are objects which were observed repeatedly by ground based telescopes but which were not correlated to a specific launch (i.e. their origin is not determined) except for the two cases listed below. Orbits were established by processing the optical measurements and propagating to the ascending node prior to (and closest to) Jan 1, 2006 00:00:00 UTC. For most of the orbits this time point is within the orbit determination time interval but for some of them it is outside due to visibility constraints of the participating optical facilities. The numerical integration model used in the data processing takes into account the Earth gravity field (16x16, EGM-96), the Moon and the Sun gravitational attraction (DE-405 ephemeris) and solar radiation pressure. The following objects were preliminary correlated based on analysis of the long term evolution:

UI036 = 1970-032A/04376 (INTELSAT 3 F-7)
UI098 = 1980-060A/11890 (EKRAN 5)

Additional photometry observations are needed in order to finally confirm this identification.

The listed orbits are a joint product of the wide co-operation of organizations including:
  • RAS Center on collection, processing and analysis of information on space debris at the Keldysh Institute of Applied Mathematics (KIAM RAS, Moscow),
  • scientific observation facilities network coordinated by KIAM RAS and Central (Pulkovo) Astronomical Observatory (St.Petersburg): Crimean Astrophysical Observatory (Nauchny), Odessa Astronomical Observatory (Mayaki), Ussuriysk Astrophysical Observatory, Maidanak Astronomical Observatory, Abastumani Astronomical Observatory, Tarija Observatory,
  • Observatory Sciences Ltd. (United Kingdom),
  • Astronomical Institute of the University of Bern (AIUB, Switzerland),
  • Space Informatics and Analytical Systems JSC.

The following data are given:

where:
  • UI.NN - number of object (UI means 'unidentified')
  • YYYYMMDD HHMMSS.SSS - date and time of ascending node crossing, UTC
  • Tnodal - nodal period, min
  • Hmin - minimal height above Earth ellipsoid, km
  • Hmax - maximal height above Earth ellipsoid, km
  • Longit - geodetic longitude at given ascending node, degrees East
  • Inclin - inclination, degrees
  • RAAN - right ascension of ascending node, degrees
  • AoP - argument of perigee, degrees
  • SemiAxis - semimajor axis, km
  • Eccentr - eccentricity
  • M - mean anomaly, degrees
The osculating orbital elements are given in the standard Earth equator J2000 reference frame. The objects are sorted by inclination. The objects UI001 to UI060 are the same objects as listed in Issue 7. Objects UI061 to UI103 are new entries.
