ASASSN1-7gf: stage A-B transition

     Berto Monard and Josch Hambsch have reported new observations.
The object showed stage A-B transition on May 16. The estimated period
of stage A is 0.05338 (5) d.
     Most of the DNe around the period minimum are WZ Sge-type one.
However, this object shows SU UMa-type superoutburst. This fact implies
a possibility that the object has a evolved core and will ultimately evolve
into an EI Psc-type or AM CVn-type object.
     Further observations are strongly encouraged.
