Ongoing Activities:

Space Link Extension (SLE) - The first version of ACE SLE was delivered to
the Library on December 14.  The delivery to the ACE MOC will not be until
after String 3 is converted to the RIONET.  

RIONet - String 3 conversion to the RIONet is on hold based on NASCOM's
schedule.    

Attitude Training - The FOT continues training on attitude determination,
maneuver planning, and maneuver execution.

Anomalies:

DOY 111 (04/21/06)  S06-0004  Ordinance Fire Component Red Limit Violation
During the maneuver, the Ordinance Fire Component violated its Red High
Limit.  This occurred because of the small jet start angle.  ORD_AB_P1 and
ORD_AB_P2 both had 1 brief red high limit violation (RH > 40).  
	2006-111 19:10:30 - 19:10:31  40.035
IMPACT:  Unknown.  This will happen when there is less than a second between
turning on the select relay and turning off select relay due to the small
jet start angle.
