1RXS J023238.8-371812: gradual brightening continues

  The object keeps a gradual brightening last week.

It is well known that rebrightening events are sometimes 
observed after main superoutbursts in WZ Sge stars. 
The current rebrightening of J0232 is , however, quite 
atypical in terms of the brightening time-scales. 
In ordinary rebrightening events, the rising time-scale 
is only ~1 day.  The slow brightening time-scale of 
J0232 implies a different nature from those ordinary 
rebrightenings.

Time-series observations are urged.  At our site, it is 
hard to take a long run for this southern object.
