Further confirmation of the ISEE-3 spin-up burn yesterday. Before the burn (actually 11 pulses on the spacecraft's hydrazine thrusters) the spin rate of ISEE-3 was 19.16 rpm. After spin-up burn it was 19.76 rpm. The original mission specifications for ISEE-3 called for a spin rate of 19.75 +/- 0.2 rpm. Bullseye.
