TL;DR: In this article, a supernova at z = 0.458 (SN1992bi) was discovered and its photometry closely matched the lightcurve calculated for its redshift from the template of well-observed nearby Type la supernovae giving a best fit value for the deceleration parameter: q o = 0 1 ± 0.3 (± 0.55) with Λ = 0, where the first uncertainty is due to the photometry of the distant supernova and the second reflects the estimated intrinsic width of the Type la absolute magnitude distribution based on nearby
