We observed GX 339-4 with the Molonglo Observatory Synthesis Telescope (MOST) on March 6. A detection was made, at a flux of 3.5 +- 1 mJy. The Swift BAT measurement, taken from the BAT team's web page (http://heasarc.gsfc.nasa.gov/docs/swift/results/transients/weak/GX339-4.lc.txt) indicates a soft gamma-ray count rate of 0.015 cts/sec/cm^2. This combination of radio and gamma-ray flux is consistent with the correlations found in previous measurements of GX 339-4 (e.g. Hannikainen et al. 1998, A&A, 337, 460; Corbel et al. 2000, A&A, 359, 251). Additional MOST observations are likely to take place this upcoming weekend. We encourage further observations at all wavelengths.
