O. B. Slee, G. S. Tsarevsky, and R. J. Sault, Australia Telescope National Facility; M. P. Rupen, V. Dwahan, and A. J. Mioduszewski, National Radio Astronomy Observatory; and D. Campbell-Wilson and R. Deacon, University of Sydney, report that the microquasar candidate reported as a radio transient by Rupen et al. on IAUC 7968 was previously detected in 2000 and 2001 by the Australia Telescope Compact Array (ATCA) as a 12.3-mJy, flat- spectrum radio source and showed a high level of variability. Further ATCA, Very Large Array, and MOST-satellite observations, spanning 843 MHz to 8.6 GHz during 2002 Sept. 3-Oct. 8, show that the new flare had a flat spectrum between 4.8 and 8.6 GHz and reached its peak of 7.2 mJy near Sept. 15, dropping to below the detection level of 0.3 mJy by Oct. 8. The flux density at 843 MHz was 1.5 mJy on Sept. 17, showing that source was optically thick at low frequencies. Tsarevsky et al. (URL given on IAUC 7968) identified this source with a relatively bright star (R = 11.4) having strong, variable H-alpha emission. Further multi-wavelength studies of this object are requested.
