As reported by R. Stubbings on October 26 in [vsnet-outburst 810], RX J2315.5-3049 experienced the other outburst. Ouda team confirmed the outburst at the magnitude of R=14.2 on October 26 (vsnet-campaign 539). On October 27, Ouda team found the object was brighter at the magnitude of R~13.6 (vsnet-campaign 542). They detected clear periodic modulations in ~3 hours light curve. The period was about 0.078 d and the amplitude is about 0.3mag (vsnet-campaign 544). T. Kato and H. Iwamatsu confirmed the magnitude is going down to about 16mag on November 1 (vsnet-campaign-dn 226, 230). T. Kato analyzed the time-series data on RX J2315.5-3049 on October 27, observed by K. Matsumoto, the Kyoto team. The analysis perfectly confirmed the existence and the phasing of humps reported. The outburst was unusually short for a superoutburst, although the detected hump signature in outburst bore all characteristics of superhumps (vsnet-campaign-dn 244).
