NOTES/ISSUES/PROBLEMS  
---------------------  
From the 9am status meeting:

2 Supports Completed in the last 24 hours (Total time: 4.6 hours)  
3 SSR dumps

CAP's / Procedures Run:  
CAP # | Time | Title / Description / Notes  
  
[893B] | 155/1130z | Disable SCS 29  
SCS 29 controls the spacecraft loads during eclipse operations and will only
be active during the entire eclipse season. SCS 107 enables and actives SCS 29
as a contingency operation. SCS 29 should be disabled when outside of the
eclipse season. This CAP should be executed after the last eclipse of the
season, as directed by the EPS engineer. Additionally, this CAP may be used in
the event SCS 107 is executed outside of eclipse season.  
  
  
[1036E] | 155/1131z | Clear EPS Glitch Counters  
The EPS glitch counters will increment if there is an issue found within the
EPS subsystem. For example, a known problem with Battery Disconnect Circuit
timing may cause occasional glitches when a disconnect pulse is detected in
the charge cycle. This CAP will dump all glitch counter values, and if a
counter increment has occurred all EPS glitch counters will be cleared.  
  
  
 
Radiation:  
Solar activity is expected to be very low with a slight chance for a C-class
flare on days one, two, and three (04 Jun, 05 Jun, 06 Jun).

MP:  
Jun0721a loads are approved, there is a TOO that if approved would interrupt schedule next week.

ENG:  
No issues.

GOT:  
No issues.
