SDSS J220553.98+115553.7: superhump period and period derivative

   William L. Stein and Nataly Katysheva (observed at Stara Lesna, Slovakia)
have reported further observations.  The mean superhump period has been
0.05806(2) d and the object appears to show a strongly positive Pdot
at +13(2)*10^(-5).  Such a large Pdot is not usually met in systems with
low fractional superhump excesses.  Further intensive observations are
encouraged!
