Abstract
We have examined 15 days of CGRO/BATSE data, obtained during the first outburst of the black hole candidate source GRO J1655-40, to search for rapid variability of its X-ray flux. We find no evidence for significant variability of GRO J1655-40 during our observations, with a 2 σ upper limit to the fractional rms amplitude in the frequency range 0.03-0.488 Hz of 6.6%. We cannot, on the basis of our observations, determine the source state (low, high, or very high state) of GRO J1655-40.Keywords
