on [<modes>]public_notice [<serial#>] [-|^]<match> { <action> }

This hook is triggered whenever a NOTICE is sent to any channel the client is on from someone not actually on that channel.

This hook will not be thrown if a matching ON GENERAL_NOTICE hook is being used in silent mode. ON GENERAL_NOTICE and ON PUBLIC_NOTICE are mutually exclusive.

To distinguish NOTICEs sent to the current channel vs. other channels:

 on ^public_notice "*" {
    if ( [$1] == C ) {
       echo +$0+ $2-
    } {
       echo +$0:$1+ $2-
    }
 }

The client does not permit any automated messages to be sent in response to a NOTICE. Any attempt will result in an error. The whole point of this is to prevent loops between clients.
