System Design Phase Approval Status
SEMP submitted to the Observatory Directors on
9/29/06 for approval
Official response not yet received (has been
requested)
– Major issue is how many $ can be made available in
FY07
Direction from WMKO management to proceed
while decision is being made
– Contracts (effective 10/1/06) to COO & UCSC need to be
worked out
