RXTE continues to monitor the millisecond X-ray pulsar IGR J00291+5934.
The X-ray flux has decayed from a maximum of 29 mCrab (2-10 keV) on Dec 3,
to less than 10 mCrab on Dec 11, 14:00 UTC.
Overall, the X-ray decay has been quite linear. However, within
the past day, the rate of decline has increased slightly. If the
decay continues on its present trend, it will become undetectable
by the PCA within 2-3 days (i.e. by Dec ~14).
