ER UMa superhumps

   Enrique de Miguel has reported observations of the current superoutburst.

Comments:     Mostly clear night + thin clouds
              Mean value of Psh=0.0616(52) d.

   His observations recorded ~0.15 mag superhumps.

   These ER UMa-type dwarf novae show rather unusual development of
superhumps.

See:

   And the behavior of stage B and C superhumps seen in most SU UMa-type
dwarf novae still needs to be investigated in these systems:

   Please continue observing by taking the present opportunity!
