CR Boo: ER UMa-like state with long post-superoutburst phase

   CR Boo has shown long post-superoutburst phase
with damping oscillation after the Feb. superoutburst
(the object is currently in ER UMa state).
Supercycle about 60 d and the duty cycle is 60% or
more. Most recent superoutburst was in early Apr.
and the object is currently oscillating in
post-superoutburst bright state.

   Similar behavior was seen in V803 Cen in 2016.
See e.g. [vsnet-alert 19830]

   This kind of behavior appears common to AM CVn
stars with frequent outbursts.
