PulCOO
Pulkovo cooperation of optical observers

  • Team of FSU astronomers and ballistics
  • 9 observing points working permanently (Pulkovo, Nauchny, Ussuriysk, Maidanak, Kitab, Abastumani, Mayaki, Tiraspol, Tarija)
  • 4 observatories are collaborating from time to time (Zelenchuk, Mondy, Simeiz, Terskol)
  • Small groups on management, technical support, software elaboration, scheduling and measurements processing, optics producing, mounts producing

+ observatory in Tarija, Bolivia (22 cm, 23 cm, 60 cm)
+ point in Paratunke, Kamchatka (10 cm, 22 cm)

PulCOO

  • ~ 30 telescopes from 10 cm to 2.6 m
  • can observe bright GEO-objects along 340 degree (in end of 2007 all bright GEO-objects along all 360 degree may be tracked)
  • ability to discover and track the faint fragments down to 20 magnitude
  • precision of measurements 0.1-2
  • sample of HEO-objects is tracked (in next year most part of bright HEO-objects may be tracked)
  • next future limited possibility to observe LEO objects

First meeting of the PulCOO Aug. 2005 Pulkovo

2th meeting of the PulCOO Jan. 2007 Zvenigorod

Dedicated Web site of PulCOO news is working since September 2006
www.lfvn.astronomer.ru
Monthly Space Debris Circular is issued since January 2007 devoted to discovered fragments

Directions of PulCOO development

  • Creation of subsystem for regular surveying of the GEO and partially HEO objects down to 15 magnitude (22-cm telescopes with FOV 4x4 degree in Pulkovo, Nauchnij, Tiraspol, Kitab, Ussuriysk, Paratunke, Tarija)
  • Creation of the subsystem for fragments observations down to 18 magnitude (producing 3 telescopes of 50 cm with FOV 2x2 degree, two 80 cm, two 70 cm, modernizations of AT-64 - FOV 2.3x2.3 degree and Zeiss-600 FOV 1x1 degree)
  • Arranging of cooperation of 1 m 2.6 m telescopes for observations of fragments down to 20-21 magnitude (2.6-m in Nauchnij, 1-m in Simeiz and Zelenchuk, 2-m in Terskol, 1.5-m in Maidanak and 1.6-m in Mondy)
  • Creation of subsystem for regular surveying HEO and partially LEO objects (4 extra large FOV optical cameras 15x15 degree in Ussuriysk, Kitab, Abastumani, Tarija)

22-cm survey telescopes: FOV>16 sq.degr.


400 objects,
3000 measurements
per night

  • 4 telescopes of 22 cm exist: Tiraspol, Pulkovo, Nauchnij, Ussuriysk
  • 2 more telescopes will be ready in August for Kitab and Tarija
  • 2 more in 2008 for Paratunka and Abastumani

Tracking of the bright GEO and HEO objects

  • 40-cm double astrographs in Ussuriysk, Kitab and Abastumani
  • 23-cm expedition astrograph in Tarija
  • 10-cm telescopes in Pulkovo and Paratunka

Subnetwork for fragments down to 18 magnitude

  • New CCD for AT-64 in Nauchnij FOV 2.3x2.3 degree
  • Two 50-cm telescopes with FOV 2x2 degree in producing for Ussuriysk and Uzhgorod, third 50-cm is in plans (the place for its installing is searched in Pacific ocean area or Europe)
  • 80-cm telescope in producing for Mayaki, second 80-cm in Terskol
  • Zeiss-600 in Tarija and Maidanak will be modernized in 2007, other two in Zelenchuk and Simeiz in 2008. Correctors and 50-mm CCD cameras FOV>1 degree
  • 70-cm AZT-8 in Gissar and Evpatoria now FOV 0.5 degree

Cooperation for tracking of the fragments of 20-21 magnitude
(jointly with AIUB team)

  • 2.6-m ZTSh in Nauchnij, 1-m Zeiss-1000 in Simeiz and Zelenchuk, 2-m Zeiss in Terskol, 1.5-m AZT-22 in Maidanak and 1.6-m AZT-33 in Mondy
  • 1-m Zeiss-1000 telescopes of ESA in Teide
  • 1-m Zimlat telescope of AIUB in Zimmerwald

Subnetwork for observations of HEO and LEO objects

4 optical cameras of 15-cm with FOV 15x15 degree with limiting magnitude 15 for 10-s exposure in Ussuriysk, Kitab, Tarija, Abastumani are ordered.
Example existing WFOC camera in Zelenchuk can observe 300-400 LEO objects per night
