Lehmann (Thueringer Landessternwarte Tautenburg,\nGermany) report:\n\nThe error box of GRB 980329 was imaged in V, R & I on March 29.8 - 30.0 UT, \nand in R and I on March 31.8 - 31.9 UT, using the Tautenburg Schmidt \ntelescope equipped with the Schmidt focus CCD camera.  Further R-band images \nwere obtained on March 31.8 UT with the 2.2-m telescope at Calar Alto, Spain,\nequipped with CAFOS. \n\nA comparison of these images shows no object in the final 1-arcmin GRB error\nbox for which the R-magnitude has declined by more than about 0.5 mag.\nBased on this finding it seems that the magnitude of the GRB afterglow\nwas R > 20 about 15 hours after the burst (or the magnitude of the optical\nafterglow did not notably vary over this time span). \n\nR-band images (gif-files) taken on March 29.85 and 30.0 UT are available\nvia anonymous ftp from \n\n    ftp.tls-tautenburg.de\n\nin the directory /pub/klose. \nFurther images will be make available, when deeper I-band images are obtained. \n\nComments are welcome.",
