VX For: now fading from the third (confirmed) rebrightening

   The mean period of the late-stage superhumps has possibly slightly
shortened to 0.06135 d (needs confirmation).

   Forwarded messages from the Hermitage team:

VX For was fading from the fourth rebrightening at CV=16 on
the Hermitage observatory run of Oct 15/16. Run is in three parts as
the observing
time was split between VX For and TT Ari.

VX For was very faint at CV=17.5 on the Hermitage observatory run of Oct 16/17.
The run was very short because the star was (too) faint and more time
was given to TT Ari.
