Scientific paper

High-time resolution photometry, performed from November 17 to December 11, 1993, on GRS 1009-45 (=X-Ray Nova Velorum 1993) reveals a V light modulation with a periodicity of 0.1996days (~4.79h). If the nature of this modulation is similar to that of the superhumps seen in SU UMa dwarf novae during superoutbursts, then the object would have the shortest orbital period among Soft X-Ray Transients (SXTs). We estimate a lower limit for the mass of the primary of ~1.6 Msun_. An optical secondary maximum or `reflare' around 90 days after the X-ray outburst is also reported. Spectroscopy during light decay confirms the presence of Balmer absorption lines with emission cores.
