Observer details:
249 SOHO. SOHO-LASCO coronagraph C2. Comet detections by X.-M. Zhou, H. Su
and R. Kracht, measurements by K. Battams, reductions by B. G. Marsden.
The results for C/2002 Q8 are remeasurements of the observations on
MPEC 2002-Q46 and MPC 46495.

R. Kracht suggested the identity of the Kracht group comets C/2002 Q8 and
C/2008 E4 on the basis of the MPEC 2002-Q46 measurements of the former and his
own measurements of the latter. He gave the previous perihelion date T =
1997 Feb. 14.9 but was unable to locate the comet on C2 images from that time.
The linked orbit below was computed by the undersigned from the measurements
given above.
