ASASSN-21gk: strange light curve

   Josch Hambsch has reported observatioons.
This object (microlensing?) has shown a very unusual
light curve.  Rapid rise on Apr. 22, around maximum
on Apr. 25, faint on Apr. 27, rapid fade on Apr. 29,
rapid rise on Apr. 30.  Such a variation would not
expected for a simple microlensing.
Spectroscopy is needed.
