General Description

K-band photometry of optically faint (i'>25), ultra-steep spectrum
 radio sources (from GMRT and VLA data).  Optical counterparts are therefore not
 visible in the finding charts (taken from very deep Subaru i' imaging, to i'~25),
 but the error circle of the radio source is indicated.  The total exposure time
 on each of our ten targets is divided into two, to remain within the maximum OB
 length of one hour.  Our ten targets are sorted into priority order.  We are aiming
 to reach a 3sigma limit of Ks~22.5 during these observations.  Photometric conditions
 are required, in seeing conditions better than 1arcsec.


The only target for which the nearby stars may be too bright is HZRGC2, for which
 the brightest star in the field has R=11.7.  

Brightest objects in each field are as follows (Rmag):
HZRGC1 16.2      HZRGC5 19.0      HZRGC9  17.5
HZRGC2 11.7      HZRGC6 18.3      HZRGC10 18.0
HZRGC3 19.4      HZRGC7 15.1
HZRGC4 18.6      HZRGC8 16.9
