The new 2meter Ritchey-Chretien-Coude telescope in the Northern               
Caucasus on the Terskol peak (near Elbrus) was put into full operation        
in late 1996.                                                                 
                                                                              
The telescope is equipped with the following instrumentation: - CCD           
Echelle spectrograph in the Coude focus; - universal UAGS spectrograph;       
- photographic camera with changeable filters; - two-channel focal reductor   
of Max-Planck-Institute for Aeronomie (Germany). The 3-camera Echelle         
spectrograph was developed specially for this telescope. It's characteristics 
are the best among the devices of the given type. The spectral resolution of  
the spectrograph is 200,000.                                                  
                                                                              
Astronomical observations at the 2-m telescope Terskol started in 1996.       
Different objects such as comets, gaseous nebulae, Seyfert galaxies, artificial
satellites etc. were observed. Unique materials were obtained in 1996-1997 by 
Prof.K.Jockers for comets Hale-Bopp and Wirtanen.                             
                                                                              
The large telescope equipped by a CCD camera allows to observe faint celestial
objects, both natural and artificial ones. So it is possible to determine     
object's coordinates and brightness using Guide Star Catalogue. This technique
was successfully applied in tracking of some geostationary satellites in      
1997-1998.                                                                    
                                                                              
All observations and tests showed that the 2-m RCC telescope Terskol is a high
manufactured instrument, which due to its optical scheme, original mounting and
control system gives great research possibilities for investigating the various
problems of astrophysics and astrometry.                                      
                                                                              
The Centre AMEI offers the use of the facilities available at the Terskol     
Observatory for research and joint work with the international community.     
                                                                              
This volume contains all images of comet 46P/Wirtanen obtained at Pik Terskol 
Observatory Longitude East 42.50083, latitude North 43.27472, altitude 3100m  
2m Zeiss Ritchey-Chretien-Coude Telescope Two-Channel Focal Reducer of        
Max-Planck-Institut fuer Aeronomie, 37191 Katlenbur g-Lindau, Germany. This   
instrument is described in: K. Jockers et al. 2001 "Exploration of the solar  
system with the Two-Channel-Foc al Reducer at the 2m-RCC telescope of Pik     
Terskol Observatory, Astron. Vestnik (Solar System Res.), in press. All images
are in FITS format.                                                           
                                                                              
2. File formats                                                               
                                                                              
  Each label file was created with the fits2pds (f2p) tool provided by the    
PDS Small Bodies Node. The name convention used is:

, where YYYYMMDD is the year (in year-month-day_of_year format), and          
HHSSFF is the time of capture. These label files point to the corresponding   
FITS files.
