We present preliminary results from the first Planetary Radar observations at the Arecibo Observatory since the upgrade. We have observed asteroids 4183 Cuno, 1994 AH2, comet C/1998 K5, the SOHO spacecraft, and Mercury using the upgraded radar. The latter two were done in both monostatic (Arecibo both transmitting and receiving) and bistatic (Arecibo transmitting and Goldstone receiving) modes. The observations of 1994 AH2 had sufficient S/N to allow some spatial resolution, and indicate an irregular object. The other minor planets were unresolved due to low S/N. The SOHO observations confirmed that the spacecraft was in its expected orbit and had a rotation period of 52.87 seconds, near its nominal 1-minute rotation period. The minor planet observations were all at fairly low S/N, and we expect to perform higher S/N observations in the near future. The system has approximately four times the pre-upgrade performance, with another factor of 2--4 expected to be achieved over the next few months.
