This nova which appeared in 1783 in the constellation Sagitta was discovered by the French astronomer D'Agelet (these observations have been discussed and published by B.A. Gould Washington Nat. Acad. Mem., Vol. 1, 1866). D'Agelet observed it on 3 days, July 26, 27 and 29, 1783 at mag 6, but calibration to today's magnitude system (Harvard visual scale) brings this up to mag 5.4 with an uncertainty of 0.4 mag.
