Hi Hakan,

  Thanks for your kind comment regarding the project. We have had a great
time since launch, examining how the spacecraft is operating.

  We have noticed this anomaly wrt the fwd/reverse power on the PA. At the
moment we have several theories, but not a total explanation.

  We have noticed that this anomaly seems to happen a min or so after the
spacecraft enters eclipse, and the fwd/ref power readings return to normal
before the spacecraft leaves eclipse. We have not yet noticed this effect
occur during daylight.

  We are continuing to investigate why this anomaly might be happening.
