1. MOIRCS Pre-imaging
■　DDT is currently very limited because of commissioning phase of 2nd generation instruments: FMOS,AO188/LGS with IRCS, HiCIAO…
■　If weather prevents scheduled pre-imaging,
　　　it is very difficult to assign it again.
⇒　We should ask all the MOS users to allow pre-imaging at 　　the end of the night.
MOIRCS:
1 hour after astronomical twilight begins
FOCAS:
30min across start of astronomical twilight
Sun Rise
Twilight begins
AG Ends

Subaru Instruments Status
4. Decommission of CISCO & AO36
■　CISCO ( )
Backup for MOIRCS in S07A
Decommissioned at the end of S07A
Will be recycled at IoA, U-tokyo.
■　AO36 ( )
Operational with CIAO in S08A
Will be decommissioned at the end of S08A.
CIAO will be still operational in S08B without AO function.
