RXTE Observations of GX 3+1
  We summarize new RXTE observations to search for millisecond X-ray variability from the bright Galactic bulge source GX 3+1. During a short 2 ksec observation we did not detect kilohertz (kHz) quasiperiodic oscillations (QPO). We place an upper limit of about 1 % (rms) on the amplitude of such oscillations.
