By fitting the observed values for 8 X-ray transients we determine an empirical relation that can be used to predict the orbital period of an X-ray transient given only its outburst amplitude: \\Delta V= 14.36 - 7.63\\log P_{orb}(h). For periods less than 12 hrs we determine a relation for the absolute magnitude of the accretion disc during outburst, which then allows us to estimate the distances to the sources.","authors_text":"E.
