The Observation Editor is used to add new observations and edit existing observations in the Observer's Log. When adding an observation, initial values are retained from the last observation added (except for User Designation, Object Designation, Rating, Notes, Image Thumbnails and Media.)
Please see a complete discussion of editing an observation in the Property Pane section of the Observation Browser.
Press OK to save changes to the observation; press Cancel to discard any changes made to the observation.
