Data Capture:  100%  DOY 165-172 2015

A successful planned failover to the ACE backup operational system
(mmocops1b) was performed on Friday, 06/19/2015.

For reference, the operational backup system underwent a series of
security patches and ACE operations (i.e, commanding and telemetry) will
be conducted on the updated/backup system for approximately the next two
weeks (leaving the primary system intact if the need for usage arises).
Following this period, the primary operational machine (mmocops1p) will
be updated with the required security patches and a transition to the
primary system will be performed.

The relevant point of contact at ASC (Dr. Andrew Davis) and White Sands/WS1
(David Venzor) were informed of the corresponding IP address changes,
required to maintain continuity of ACE data product delivery.
