A renewed optical and X-ray outburst of the Black Hole candidate XTE J1118+480 is reported in ATEL#383 and ATEL#384. A radio observation at 15 GHz was made with the Ryle Telescope at Cambridge from 2005 Jan 12 21h59m to Jan 13 09h57m (UT). The mean flux density was 8.7 mJy, with an increase of about 10% during the 12-h observation. This flux density is close to the mean (9.0 mJy) found during observations of the previous outburst in 2000 Mar - Jun.
