V592 Her: possible superhumps?

   According to AAVSO observations, there seems to be some indications
of very low-amplitude periodic modulations.  A preliminary analysis
of the available data has yielded a period of 0.05654(3) d, which
is close to the superhump period obtained during the 1998 superoutburst.
Since the amplitude, however, is very low (less than 0.01 mag in average),
the existence of the periodicity needs to be tested by further continuous
observations.

   There is no clear indication of a rapid fading expected for a normal
outburst.
