Gaia19fdx: SU UMa-type dwarf nova

   Crimean Astrophys. Obs. team reported observations
between Nov. 24 and Dec. 5.  The object showed superhumps
on Nov. 24 and 25, but the duration of observations
was too short to determine the period.
The object faded from the superoutburst between
Dec. 2 and 5.  Observations on Dec. 1-2 showed
short-term modulations with a period of ~0.02 d,
which may have been a harmonic of the superhump period.

   The object was observed earlier (Nov. 19-21)
by Tonny Vanmunster and Itoh-san without detecting
superhumps.

   The preferred superhump period from the available
observations is 0.070 d, but this requires confirmation
by further observations.
