MASTER OT J191841.98+444914.5: likely AM CVn-type superoutburst

   Tonny Vanmunster and Ian Miller have reported
observations.  The data show clearly periodic variations
with a period of 0.0222(1) d and a mean amplitude of
0.10 mag.  Although the double period may not be
excluded, the present data suggest that the basic
period is 0.0222 d.  This object is likely an AM CVn-type
object currently undergoing a superoutburst.
Further observations are very strongly encouraged.
