ASASSN-18fs: stages A and B, early superhumps and q

   Peter Starr has reported a complete coverage
(via the AAVSO database).  Berto Monard also reported
further observations.
It has now become apparent that stage A lasted
between Apr. 6 and 10.  The period was 0.06115(2) d.
The current period (stage B) is 0.05983(1) d.
The period of early superhumps was 0.05933(5) d
(full amplitude 0.025 mag).
The mass ratio derived from these values is 0.081(3).
The object may show multiple rebrightenings and
further observations are strongly encouraged.
