J. Halpern & E. Gotthelf (Columbia U.), C. Martin & B. Kern (Caltech), report:

"We obtained a 600 s R-band image of the joint RXTE/IPN error region of
GRB 981220 (GCN 159Not found
 
 
,160Not found
 
 
) on the Palomar 5m telescope on Dec 23.15.
The limiting magnitude was about 22.7.  Preliminary analysis shows
no new object in comparison with the digitized POSS II plate to a limit
of R=20.5.  Our image is posted at
