   The object is identified with the following:

USNO0825.15465079 192035.000 -035750.91 (2000.0) 11.7 15.4
192034.1 -035756 (2000.0) IRAS19179-0403 1.628 0.698 0.400L 2.562L 15%
192034.1 -035756 (2000.0) SSC19179-0403 1.628 0.698 0.400L 2.562L
192033.0 -035620 (2000.0) WSV102

   The last entry WSV102 corresponds to a variable star discovered by
Wakuda No. 102.  The coordinates for WSV102 are approximate, but is
very likely identical with the variable mentioned.  Wakuda's discovery
was made photographically.
