1RXP J113123+4322.5 superhumpe period change, update Dear Colleagues, We have further received new data from Jochen Pietz. We have further undertaken the analysis of the Kyoto and RIKEN data. The data up to now firmly confirmed the lengthening of the superhump period. The behavior very strongly resembles that of SW UMa. The period derivative is as large as dot(P)/P = +8*10(-5) (the value in the preceding posting was probably in error). We can very much expect similar phenomena observed during the later course of superoutbursts in SW UMa, WX Cet, V1028 Cyg etc. Further long, continuous observations are encouraged.
