J. L. Sokoloski, Harvard-Smithsonian Center for Astrophysics; and M. P. Rupen and A. J. Mioduszewski, National Radio Astronomy Observatory, on behalf of a larger collaboration, report the detection of the symbiotic star AG Dra in the radio with the Very Large Array (in BnA configuration) on Oct. 7 UT, roughly nine days after the start of an optical outburst. The radio source was not resolved, with a beam size of 0".84 x 0".44 FWHM at p.a. 32 deg. The 8.46-GHz flux density was 0.47 ± 0.09 mJy. The nominal 4.86- GHz flux density was 0.17 ± 0.07 mJy. However, as this 5-GHz flux density was comparable to background fluctuations, it is most conservatively interpreted as a 3-sigma upper limit of 0.38 mJy. In either case, the 5-GHz flux density has decreased with respect to the value of >/= 1 mJy found by Ogley et al. (2002, MNRAS 330, 772) in Mar. 2000, when AG Dra was in a quiescent state after a series of optical outbursts. Previous low 5-GHz flux densities were reported by Seaquist and Taylor (1990, Ap.J. 349, 313), when AG Dra was near the peak of a large optical outburst in 1982 (</= 0.41 mJy) and when it was near the tail end of an optical outburst in 1986 (0.36 ± 0.08 mJy).
