ASASSN-14ag: deeply eclipsing SU UMa-type dwarf nova

   As already reported by Gianluca Masi, this object is
a deeply eclipsing SU UMa-type dwarf nova.
The observation has confirmed the identification
of the period in vsnet-alert 17036.
The updated ephemeris of the eclipse is:

Min = BJD 2454413.99182(7) + 0.060310644(2) E

   The next superoutburst of this object will deserve
a further study.  The short orbital period suggests
that this object will show typical stage A-B-C
superhumps.  Observations of the eclipses will
enable us to trace the variation of the disk radius
and will shed light on the still unknown nature
of stage B-C transition.  Such observation
might be possible for XZ Eri, but ASASSN-14ag is
brighter than XZ Eri by two magnitudes!
