Following a slow fade this nova reached an initial minimum of
around visual magnitude 13.8 on 1993 August 2. However subsequent
results suggest that it is again brightening:

          8.854,   15.5pv(Nick James, Chelmsford, UK)

WW VUL
Bjorn Granslo, Blindern, Norway e-mails that he has observed this
eruptive star unusually faint:
1993 Sept 5.008UT, 12.2v (0.203-m T, sequence AFOEV)
Margareta Westlund, Sweden and M.Moriyama, Japan have confirmed
this fade from a 'normal magnitude' of around 11.0:
