[vsnet-outburst 18854] ASASSN-15si

ASASSN-15si

   According to Maeda-san, this object faded to 19.3 mag
on Nov. 3.  Tonny Vanmunster also reported rapid fading
with modulations (unrelated to orbital humps?).
The fading rate is too large for an ordinary dwarf nova.
The blue colors in the SDSS data may suggest an AM CVn-type
object.  Spectroscopic observations are encouraged.
