personnel - some 24 hrs per day 7 days per week and some between 8-22H

as on work days from 8-22H EDT/EST. To the extent possible please
submit such triggers/requests during normal EDT/EST weekday working hours.
Peer-reviewed TOOs are TOO proposals that were submitted and accepted
as a result of the Chandra Call for Proposals (CfP). Since their
scientific objectives have already been approved, we require only
confirmation of a few details and a brief description of how the trigger
criteria has been met. Please use the form below to identify the TOO

If you are unable to use this form to trigger your TOO, please contact
Unanticipated TOOs are charged to Director's Discretionary Time.
These will not have not been previously accepted through the Chandra Call
for Proposals. For the unanticipated TOOs, a compelling scientific case
must be made for inserting them into the mission timeline.
