Abstract (from CDS):

begin{HTML} We photometrically observed a 2003 June superoutburst of GO Gom. The mean superhump period was 0.063059(13)d. The resultant data revealed that (1) the obtained light curve contained a precursor, (2) a plateau stage of the object lasted for 8 days, which is remarkably shorter than that of ordinary SU UMa-type dwarf novae, and (3) the amplitude of the superoutburst was less than 5mag, which is unpredictably small when taking into account the fact that the supercycle of GO Com is about 2800 days. In order to explain these anomalies, a mass-elimination process from the accretion disk, such as evaporation, may play an important role.
