ASASSN-19rx: orbital period

   Crimean Astrophys. Obs. team observed the rising
part of an eclipse on Aug. 4.  The orbital period
is confirmed to be half the initial period
(see vsnet-alert 23451 ASASSN-19rx: update orbital period).
My revised O-C analysis gives candidates periods
(in the order of increasing residuals):
2.4649, 2.4689, 2.4609, 2.4729 d.
These periods give essentially the same phase diagram
for recent time-resolved observations and a longer
baseline is necessary to distinguish them.
