We determine R = 23.7 $\\pm$ 0.5 mag on 29.89 March, which is consistent with R = 23.6 $\\pm$ 0.2 mag as reported by Palazzi et al. (1998) on 29.99 March. Based on extrapolations of the light curve we claim that the R-band magnitude of the GRB 980329 host galaxy should lie in the range 26.8 mag $<$ R $<$ 29 mag. We also discuss the similarities with GRB 970111.", "revisions": [ { "version": "v1", "updated": "1999-06-11T20:26:30.000Z" } ], "analyses": { "keywords": [ "optical counterpart", "early detection", "second earliest detection", "report optical observations", "error box" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "inspire": 501605 } } }
