Lewis Swift discovered NGC 5778 = Sw. IV-15 on 20 Jun 1886 and recorded "eeeF; pS; R; pB * close f; ee dif." His position is just 9 sec of RA west of UGC 9590 and the description applies to this galaxy. Bigourdan measured an accurate position on 19 May 1890. UGC fails to label equivalent UGC 9590 as NGC 5778. See identification notes on NGC 5825.
