   RS Oph is fading.  The present faintness is comparable to the
post-outburst transient fading (around 2006 July).
The latter has been interpreted as a result of temporary
disappearance of the accretion disk.  The same interpretation
appears difficult at this epoch.  Time-resolved photometry is
encouraged to see if flickering is still present.
