The final part of the basic TASK configuration is the status.  This is a description of the data entry necessary to end a TASK definition, although this final step can also be done later directly from the Project panel.    See >>How to create a new project<< and >>How to add an observation to a project<< for the first part of the task of defining a new TASK.

While editing a TASK, select the "Status" panel: 

You will immediately see a big panel indicated whether your TASK has not been activated and is not in the schedule queue of the telescope


or whether it is

You can now change the activation status or wait until later.
