Please observe ASAS J071404+7004.3

  (Changed from GSC4364.1209 in vsnet-alert 23944
since the discoverer became evident).

   This object is an IW And star and currently
in standstill at least since 2019 Sep.
Our aim is to see whether this object shows
negative superhumps as in IM Eri, which showed
negative superhumps during the standstill state
in the past
(see https://ui.adsabs.harvard.edu/abs/2019PASJ..tmp..135K/abstract
for information).

   Tonny Vanmunster has already reported observations.
Since this star is bright (11-12 mag), small telescope
even under strong moonlight can sufficiently contribute
to this study.  The orbital period is expected to be
several hours.
