ARCA Supernova monitor points to ORCA
The link to the Supernova monitor from the wiki at https://wiki.km3net.de/index.php/Operations/Operations_Manual/Remote_Access_KM3NeT_IT points to http://antorcamm2.in2p3.fr/supernova/ SN Monitoring (access with the generic km3net account) which actually corresponds to ORCA. Idem dito, the link under button SN at http://arca.mon.km3net.de/ points to http://antorcamm2.in2p3.fr/supernova/
