Hi all -

Let's say that we have a 75 meter carbonaceous chondrite headed for the Earth. Let's say that we have both Pan-Starrs and LSST in place.

Would either of them be able to detect the approaching Tunguska type impactor in time? Would it reflect enough sun light for their CCDs to detect? If so, how many hours or days of warning would we have before the impactor's arrival?

Couldn't Moon based systems provide a longer warning time?
