The 2002 Eastern Mediterranean event, the 2002 Vitim event (Russia) and the Chelyabinsk meteor (Russia, February 2013) were not detected in advance by any Spaceguard effort. On October 6, 2008, the 4-meter 2008 TC3 meteoroid was detected by the Catalina Sky Survey (CSS) 1.5 meter telescope at Mount Lemmon, and monitored until it hit the Earth the next day.
