Because of phase-lock problems with the Cesium clock, we have been operating with the crystal oscillator only over the past two weeks, resulting in extremely high clock drift rates. Unfortunately, we have been unable to fix this problem and have been forced to replace the Cesium clock with a small portable Rubidium clock. The replacement clock was installed at 20:40 UT, Mar.12 (DOY 071), 1993. This clock will now serve as the reference frequency standard until the Cesium clock can be repaired.
