Notes: 2007 FD was discovered with the Spacewatch 0.9m telescope on 16 March 2007 and announced the next day, which is when JPL posted it as an impact risk. NEODyS posted it on March 18th.
After the Spacewatch 1.8m telescope closed out the discovery confirmation process on March 17th, this large object wasn't reported observed again until an update MPEC was posted late on April 17th with recovery observations from the Mt. Lemmon Survey and the Spacewatch 1.8m telescope during 14-16 April. And JPL and NEODyS removed 2007 FD as an impact risk on April 18th UTC.
On May 25th another update MPEC reported that Rob Matson had found 2007 FD in the archives from the Siding Spring Sky Survey from 13 Aug. 1982 and from NEAT's Hawaiian telescope on 24 Feb. and 20 and 29 March 2001.
