Nah, this is a too small impactor to be part of spaceguard and the other 
NEO programs (their cut-off is around 140 meters). This size will 
typically be picked up by radar or observations during the final plunge, 
if they are detected at all. As I argue in my commentary
looking for them is not a bad idea, but it is not a major way of 
improving planetary safety.
