Activities:

Data Capture:  100%  DOY 173-180 2014

DSN is implementing a change that should resolve the intermittent
problem with the Earth Receive Time.  ACE receives 1 telemetry frame
every 0.091 seconds (high-rate) and the DSN Earth Receive Time is
occasionally be behind by 1 or more frames after a data rate change.  An
incorrect Earth Receive Time from DSN results in clock reports sent to
ASC and NOAA SWPC being slightly off by a fraction of a second.  This
issue (AR 118839) started with version 11.3.6 of DSN's Receiver,
Ranging, and Telemetry (RRT) software that is in SOAK at Goldstone.  The
new change has been implemented for the Chandra mission, which had the
same problem.  The next Goldstone pass is on Friday 7/4/2014.

There is no DSN pass for Thursday 7/3/2014 DOY 184 (as measured by UTC)
and 2 passes for Friday 7/4/2014.  There will be no clock report or
attitude report for this coming Thursday.
