Dear colleagues, We obtained unfiltered photometric data of GO Com in June 5.504-0.729 (UT) at Hida observatory with a 60cm telescope. The superhump amplitude was 0.2-0.25 mag, siginificantly smaller than that reported yesterday. Our data seem to show that the decline rate suddenly became larger (to larger than 1.0 mag/day?) around 5.65 (UT). Do anyone confirm this trend? Best regards, Daisaku Nogami
