Hello,

Unfortunately, we were not able to collect data for occultation #7.  The
DSP was not functioning properly.  When we asked the station to reboot,
they only rebooted part of the DSP -- the RSCP but not the SPA-R. (The
SPA-R controls the POCA.  A request for the station to reboot the DSP
usually includes both.) We had no indication that the SPA-R had not been
rebooted until we went into run mode.  Since the SPA-R, and thus the
POCA, was not working properly, we only saw the signal on the edge of
the bandpass, then it disappeared.  We could not enter a frequency
offset because we could not communicate with the SPA-R.

DR # L01779 was opened.  This was DSS-54.

Tonight's occultation is over DSS-65 at approximately 1:30 AM.  We will
make sure that both the RSCP and SPA-R are rebooted at the beginning of
the pass.

-Trish
