Scientific paper

We report further radio observations of the X-ray transient and black hole candidate IGR J17464-3213 = XTE J17464-3213 (ATEL #132; ATEL #133; IAUC 8105) from the Very Large Array (VLA). The source continues to brighten, and appears now to be doubling in flux density every two days. Observations on 4 April 2003 UT give flux densities of 20.0+/-0.2 mJy at 4.9 GHz, and 22.1+/-0.2 mJy at 8.5 GHz. The radio spectrum has remained remarkably constant at nu^+0.2, characteristic of optically-thick synchrotron emission.
