Castro-Tirado (LAEFF-INTA, Madrid and IAA-CSIC, Granada) report:
We scanned at 8.42-GHz the position of the afterglow reported for
GRB 991208 (GCN 451) with the 70-m radio-telescope of the Madrid Deep
Space Communication Center (MDSCC, NASA-INTA) located at Robledo de
Chavela, Madrid. The observations were based on two observing runs
carried out on Dec 22.2491-22.6488 UT and Dec 23.3243-23.6095 UT 1999.
We derive a 1 sigma upper limit for the flux density of 3.5 mJy for
the afterglow. The authors wish to thank the MDSCC staff and the JPL
scheduler for their enthusiastic support.
