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

  Josch Hambsch has reported observations on two nights.
The object shows both superhumps and deep eclipses
(0.8 mag).  The orbital period is somewhat longer than
0.07 d.  I'll inform more details later.
(Currently the time resolution was not sufficient to
resolve the eclipses).  Observations from other southern
observers are welcomed.
