Targets of Opportunity

Last Updated: 2014/10/15

Suggestions for Target of Opportuntiy (ToO) observations will be considered for exceptional opportunities. Due to the constraints in operations funding, even some exceptional observations may not be possible to implement.

A "fast" ToO is defined as a requirement for observation within 48 hours of notification. These are particularly difficult to implement. ToO observations with longer lead times are less intensive for the operations team.
