TCP J18154219+3515598: growing superhumps

   Javier Ruiz, Geoff Stone and Tamas Tordai have
reported new observations.  The object shows growing
stage A superhumps.  The mean period is 0.06338(2) d.
It was most likely we missed the phase of early
superhumps.  The resultant superhump period suggests
a system with multiple rebrightenings and/or a period
bouncer.  Further observations are very important.
(Even if we missed early superhumps, we can still
reasonably constrain the mass ratio if post-superoutburst
superhumps are measured).
