Object Names in the Security Audit Log

I’m doing some auditing on our servers, and having a little trouble reading the logs. See the Object Name on line 4? I need to know what the English name is for this object. Is this a security object ID or something? Is there a way to figure out what it is? Any help would be appreciated….
