Orbital parameters

Enter either satellite ID or name. If exact name will not be found, substring search will be used to show candidates. Use checkboxes to select various variability classes or object types. Specify the period to refine search of satellites with periodic light curves. Read the short description also. Please note that all the satellites with CIS country code (i.e. Russian etc) are hidden from the list! If you have any questions or wish to use the data in your research, please contact Elena Katkova, who is the primary person behind the database, using e-mail address mmt.satellite@yandex.ru

Description of the database

The database contains the satellites observed by MMT and identified using publicly available TLE data. The standard magnitudes (corresponding to the phase of 0.5 and the distance of 1000 km outside the penumbra) have been computed for every satellite, and rough classification of its variability is performed.

  • Periodic - significantly periodic light curves
  • Aperiodic - stochastic brightness variations or not enough data to estimate the period
  • Non-variable - brightness is not varying significantly

You may use the search fields and checkboxes to search using either satellite catalogue ID or name, and to filter the results according to variability class and/or range of periods.

The satellite information includes its catalogue ID and name, launch date and standard magnitude averaged over all available non-penumbral observations. Every track contains information on the distance and phase angle changing during the passage of satellite through MMT field of view, as well as its apparent brightness and standard magniude.

Symbols used:

  • - identified using NORAD TLE
  • - identified using McCants catalogue
  • - observed while in penumbra
  • - observed outside the penumbra

The objects are classified as follows:

  • U/SAT - Uncertain Satellite
  • ACT - Active Satellite
  • INACT - Inactive Satellite
  • R/B - Rocket Body
  • DEB - Debris
  • M/DEB - Mission Debris
  • F/DEB - Fragmentation Debris
  • UNIDENT - Unidentified

Photometric measurements are performed either in standard Johnson-Cousins BVR filters, or, more frequently, in a white light. In the latter case, the magnitudes are calibrated to V one using field stars.

Radar Cross-Section data are taken from the publicly available list at CelesTrak.
