2008 G2 (199P/Shoemaker)
Whilst examining single-night observations of minor planets from 10 April
1994reported by the Catalina Sky Survey to the Minor Planet Center, T. B. Spahr
identified a candidate for comet P/1994 J3 = 1994k = 1994 XXVIII (Shoemaker, a.k.a.
Shoemaker 4; cf. IAUC 5991, 5998, etc.).
The comet was around 19th magnitude at recovery, near its brightest for its reaches
perihelion in 2009 April. Spanish CCD observers reported the comet in outburst in
early August, and this was confirmed by other CCD observers.
