Ship Oslo, Line Stjerne, Nov 30, 1910

I find this ship listing on the emigration register, (link below) but am not finding it listed in the ships or lines on this site. Does that mean that it just hasn't been added yet, or something else? It's the first ship/line I haven't found here ... Thanks! http://digitalarkivet.uib.no/cgi-win/webcens.exe?slag=visbase&sidenr=22&filnamn=EMITROND&gardpostnr=150472#nedre
