I see on MPML today that some prediscovery images of 2007 WD5 have been found. Adding those to the orbit solution appears to have increased the chances of impact to 1 in 25. Still a long way from certain but it is the first time I can recall that prediscovery images have increased the chances of an impact. patrick
