GO Com rare outburst! As reported by Christopher Jones (vsnet-outburst 5622), the suspected large-amplitude SU UMa-type dwarf nova GO Com is undergoing a bright outbust (mag 13.0-13.5, depending on observers). The most recent confirmed outburst was in 1998 April. The only likely superoutburst recorded in this decade was in 1995 August (Kato et al. 1995, IBVS 4228), which apparently showed a precursor outburst and a rebrightening. The 1995 outburst was not sufficiently followed to determine the superhump period because of the short visibility. We must also note that GO Com was once considered as a WZ Sge-type candidate; this also needs to be tested. The present outburst is as bright as the 1995 one, and the present excellent visibility will certainly allow us to make first-time detailed time-series photometry! Please observe GO Com as the first priority target. More information will be informed later. Regards, Taichi Kato VSNET Collaboration team
