ASASSN-20if: growing superhumps were caught

   Josch Hambsch and Berto Monard have reported observations.
There were no superhumps on July 18 by Hambsch, but later
on July 18 low-amplitude superhumps emerged (Monard).
We thus have recorded stage A superhumps reasonably well.
Further observations will be very important to study
the evolution of superhumps, since long Porb systems
with rare outbursts tend to have long durations of stage A
(resembling WZ Sge stars).  The current superhump period
is 0.08794(8) d (shorter one in vsnet-alert 24456 is correct).
