Apparent Close Approaches of NEAs to the Stars for December 2023
       Observatory  C20 Kislovodsk Mtn. Astronomical Stn., Pulkovo Obs. 

The list of apparent approaches of Near-Earth Asteroids to the UCAC4 catalog
stars.  Within  some  time span an asteroid moves near two stars so that the
angular  distance  between the objects does not exceed some predefined value 
(in our case 30 arcseconds).  The arcs of the spherical triangle sides being 
measured  it's  possible  on  the  base of the catalog data to determine the  
coordinates of asteroid. The first line of the output data shows the number,
name  and vis.mag. span of asteroid. Other lines include the time span (UT),  
catalog  numbers  and  visual  magnitudes of stars. The magnitude difference 
between the objects usually is not more than 0.5.
