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
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
