We report optical observations of the GRB 980329 error box which represent the second earliest detection of the GRB 980329 optical transient. We determine R = 23.7 0.5 mag on 29.89 March, which is consistent with R = 23.6 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.
Key words: methods: observational gamma rays: bursts
* Based on observations carried out at the 1.0-m Jacobus Kapteyn Telescope operated by the Royal Greenwich Observatory in the Spanish Observatorio del Roque de los Muchachos of the Instituto de Astrofísica de Canarias.
