    The nearest USNO stars is located at:

   153926.298 -521918.85 (2000.0) 18.2 19.4

    This figure is moderately outside Liller's error box.  This star is
one of two stars described to be possible quiescent counterpart.
Would this mean the quiescence is below the plate limit (fainter than 20?)
-- then what a surprize for a recurrent nova!  But this seems to explain
the observed lack of emission lines in the supposed quiescent counterpart.
