Recovery: ( IAUC 9077 )

Jim Scotti recovered P/2004 EW38 with the 1.8-m Spacewatch telescope at Kitt Peak on September 21.37, noting only stellar appearance. The indicated correction to the orbit prediction on MPC 59600 is Delta(T) = +0.02 day.Following publication of the new orbit, Maik Meyer was able to locate images of the comet on Haleakala-NEAT images taken on 1997 January 15. Due to the mediocre quality of the images a decision on whether the object showed cometary activity was not possible. The magnitude was around 19.
