I approve IBEX_2024_153_o0650a_v001.scr. Ken and Ryan have also checked the unexpected battery charge constraint violation and there is definitely no eclipse taking place then since the Sun and Earth vectors are close to 90 deg apart. We have seen odd battery charge constraint violation values in the past so the consensus is that this is a modeling error.

==========================

HARD CONSTRAINT VIOLATIONS

==========================

NO VIOLATIONS.

 

==========================

        SOFT CONSTRAINT VIOLATION

==========================

 

I saw this violation IBX-CLC-015. I looked for any small eclipses or close transmitter times. We never drop to zero. I can’t explain why this is flagging other than maybe an MPS miscalculation.

 

IBX-CLC-015: Battery charge falls below minimum from 2024/06/02 04:43:00 UTC -

             2024/06/02 14:04:00 UTC. Lowest charge level is 3736.960000

             watt-minutes during this interval.

IBX-CLC-016: No command to enable spin pulse protection was found after

             transition to science mode at 2024/06/02 07:01:28 UTC

IBX-CLC-016: No command to enable spin pulse protection was found after
