ASASSN-21hc: suspected AM CVn object

   Josch Hambsch has reported observations on five nights.
The object faded rapidly on May 10, 0.6 mag in 0.2 d.
The fading rate is compatible with an AM CVn object.
A period analysis yielded a possible weak signal
at 0.050 d, but this may have been spurious.
The object is expected to brighten again and continued
observations are requested.

   Spectroscopy is urgently needed.
