  The current mini-outburst of GRO J0422+32 (USXT) is now turning
  to an end, with an astonishingly rapid decline rate of 0.5 mag/day.
  The system reached V=17.7 on Jan. 2.

  Accompanied by a general fade, a possible dip with an amplitude of
  0.2 mag seems to be emerging.  The light minimum occurred on Jan. 2.588
  UT, coinciding with the minimum of the sinusoid-like modulation
  (presumably orbitally originated).  Suggestion of an eclipse of the
  hot spot?
