B, V and R optical photometry performed on the field of the GRB 970111 soon after its detection by BeppoSAX is presented. No remarkable optical object is found inside the corrected error box. The optical counterpart of an X–ray and radio source and a suspected red variable (probably an eclipsing binary) have been detected inside the field of GRB 970111.

The black hole candidate LMC X-3 varies by a factor of four in the soft Xrays on a timescale of 200 or 100days (Cowley et al., 1991). We have monitored LMC X-3 with RXTE in three to four week intervals starting in December 1996, obtaining a large observational database that sheds light on the nature of the long term Xray variability in this source. In this paper we present the results of this m...
