On April 10 2008, Tim B Spahr at the Catalina Sky Survey at the Minor Planet Centre, identified a candidate for comet P/1994 J3 = 1994k = 1994 XXVIII, aka Shoemaker 4, discovered in May 1994 by Eugene Shoemaker. Brian Marsden also identified another candidate in the Catalina observing data, dating April 01. In both cases, the observer was Richard Kowalski. The comet was approximately at magnitude 18 at the time of the recovery and close to its maximum brightness at this opposition. The orbital elements of the comet P/2008 G2 (Shoemaker) indicated a perihelion passage on April 09, 2009 at a distance of 2.9 AU from the Sun, and 14.5 years period.
